a3b551ab2f Fix bug in the ARM full code generator for inlined count operations. 
The inlined add needs to set the condition codes to correctly detect
smi overflows.

559ba2ccf0 Don't share function result caches between contexts. 
A reference to the caches array was embedded directly into the builtin
code and this allowed sharing objects between contexts.

Unfortunately, clearing the cache on GC won't prevent sharing so we
either have to have per-context builtin code or load the cache
indirectly from the current context. This change implements the second
approach. The first approach may be interesting to consider in the
future for some perfomance critical functions, and the current
approach can still be improved by putting the caches directly into the
global context (or even global objects).

3ca99e722b Fix BinaryOpIC implementation on ARM. 
On a pair of smis HEAP_NUMBERS stub is significantly slower than GENERIC. This slows
down some tests dramatically (crypto-aes from SunSpider).
With this change HEAP_NUMBERS stub switches to GENERIC stub the first time it sees 2 smis
as its operands.

931f0a031a Changed inlined property load detection on ARM 
Instaed of having a nop after all non-inlined calls to load IC use a different nop (mov r1, r1 instead of mov r0, r0) to detect an inlined load IC.

Added more infrastructure to the deferred code handling to make it possbile to block constant pool emitting in a deferred code block, including the branch instruction ending the deferred code block.

Addressed a couple of comments to http://codereview.chromium.org/1715003, including adding an assert to make sure that the patching of an ldr instruction is always possible.

cb27d09534 Fix bugs introduced by r4475: 
- RelinkPageListInChunkOrder might relink unused pages into the middle of a sequence of used pages. Filler objects should be placed at the beginning of such unused pages otherwise generic iterators (e.g. HeapObjectIterator) would not handle them correctly. 
- ObjectAreaEnd() should not be used as an allocation limit for pages from FixedSpace. Pages in such spaces do not use top page_extra_ bytes of object area.

b8ba4deacc Reapply: Inline fast cases in string keyed load IC. 
(Fixed handling of out-of-bounds keys.)

String keyed load used to call STRING_CHAR_AT builtin that performs
two steps (get a char code, construct a one-char string from the
code), both of which have fast cases implemented as inline runtime
functions. In this chage most of the code from these functions is
extracted to a set of common generator functions in StringStubBase and
the fast cases are grouped together in the IC code.

afc15bb48f Reapply load ICs for nonexistent properties. 
We need to be careful to check global property cells for the property
encountered during lookup.  Therefore, the ICs have to be specific to
the name of the property if global objects are involved.  In
principle, this means that we could get a large number of monomorphic
ICs for the same map if there is a global object in the prototype
chain.  However, since this is only done for normal load ICs and not
for keyed load ICs I do not expect this to be a problem.  I will
experiment with it once this goes in.

09aa20da08 Ensure stack alignment in ARM port 
In the CEntryStub keep track of the actual skew from the correct alignment to ensure proper alignment before calling the runtime. Add checks to test the expected skew when running on hardware.

Use the PrepareCallCFunction/CallCFunction in a few other places.

Add check to the ARM simulator for correct alignment.

Add option --sim-stack-alignment to set the stack alignment in the simulator. Currntly only values 4 and 8 makes sense. 8 is the default to make snapshots generated with the simulator work on hardware requiring 8 byte stack alignment.

fbefa72f81 Simple register allocation for ARM. Only top of expression 
stack for now.  Next step is probably fixing the binary
op stubs so they can take swapped registers and fixing
the deferred code so it doesn't insist that all registers
except the two operands are flushed.  Generates slightly
worse code sometimes because the peephole push-pop
elimination gets confused when we don't use the same
register all the time (the old code used r0 always).

4f5ff869d3 C++ profiles processor: align browser mode with the old implementation, sample VM state. 
In browser (DevTools) mode, only non-native JS code and callbacks are reported.
Also, added "(garbage collector)" entry which accumulates samples count in GC state.
Trying to display "(compiler)" and "(external)" only brings confusion,
because it ends up in displaying scripts code under "(compiler)" node, and DOM
event handlers under "(external)" node, which looks weird.

789f832e4a Move the AstVisitor stack check from Accept to Visit. 
The stack check has been moved from the Accept function dispatching on
the AST node type, earlier to the Visit function dispatching on the
visitor type.

This allows very simple non-recursive visitors (not taking extra
arguments or returning values) via the convention of calling "Visit"
if one wants the stack check and "Accept" if one does not.  Recursive
calls should all be via "Visit".

81779f6324 Rework flow graph construction. 
The flow graph has been simplified to remove the special branch, join,
and exit nodes.  All nodes are now basic blocks (possibly empty to
preserve edge-split form) with a distinguished entry and exit block.

Most trivial expressions are not added to the flow graph as
instructions.  The assigned variable analyzer has been changed to
sometimes work right-to-left so that right subexpressions can be
marked as trivial.

The reaching definitions analysis has been temporarily removed, and
the analyses that depended on it (primitivity analysis, dead code
marking) as well.

That shouldn't be the problem for paged spaces as objects in those

I did not implement tests covering calls with undetectable parameters since I would need to make these tests native. Just thought it was not worth the effort. If you think tests would make sense, I can add them. We might want to allow other functions to receive undetectable parameters, but I am not seeing any good candidates.

54f0a5b221 Expose debug context into the native code. This change is doing several things: 
1) Exposes Local<Context> v8::Debug::GetDebugContext().
Rationale: We can already get debugger context instance using various workarounds,
so exposing it explicitly in the API only makes things more clear.

2) Removes debugger.HasJavaScriptFrames() requirement for entering debugger context.
Rationale: Sometimes we'd like to call into debugger from the external native code.

3) Makes Debugger v8::Debug::Call execute on debugger context's global object.
Rationale: This is somewhat arguable, but temporary measure. We've agreed that we
should introduce a DebugAPI object that would expose necessary API in the debug-delay.
The problem is that it would take some time to define this API and it is not really
convenient to do that on the v8 land given the difference in v8 / host lifecycle.
The plan is to compose this API as a Debug.* wrapper outside v8 by means of exposing
debugger context's global object here, and once API settles down, upstream it to v8 and
start making Debug::Calls on this new DebugAPI object instead.

3672624b45 Fix pop push optimization to work with partial snapshots (correct 
registration of external references in Proxy objects).
I moved the declaration of the two functions to stub-cache.h
because with all the types they use it's hard to declare them
anywhere else.  But the actual definition is still in runtime.cc
near to the place where they are used.

Previously we marked compare operations that occurred as for loop
conditions so as to avoid inlining the floating-point code for them.
Begin marking all expressions that occur as any loop condition
(because they are never dead code).

04a5802d80 Add iterative primitive type analysis. 
This change adds a data-flow pass to statically determine
if a variable contains a primitive type.

It requires building the flow graph and computing reaching
definitions as pre-requisites. The analysis annotates all
VariableProxy nodes with the result.

9240342ad6 Inline floating point compare 
Inline floating point compare instead of calling the stub when the following conditions are met:
  * Code is in a loop
  * Compare is not a for loop condition
  * Compare is not an equal comparison

This inlined code handles heap number to heap number and heap number to smi compare. It can also handle smi to smi compare, but whenever there is a chance of comparing two smis the smi compare is inlined before the inlined floating point compare. Support for non SSE2 hardware is included.

A new set of variants of the compare stub without the floating point comparison code is called if the inline comapre fails due to the operands not beeing heap numbers or smis.

The virtual frame has been extended with a branch taking two live results to be carried through to the destination. This makes this change much simpler as the inlined code have two live results in registers and a number of bailouts.

CompareStub::GetName needs to be updated as well. I will do that as a separate change.

Also inlined equality check if both operands can't be NaN. This can only provide positive equals if it is the same object.

Use the classical worklist algorithm to compute reaching definitions.
All nodes are initially put on the worklist.  Until the worklist is
empty, nodes are removed, their RD_in is recomputed, and if it changes
their successors are added to the worklist.

With my previous change to limit memory for object literals, we get more slow-case elements and this makes up for the slowdown when loading from those slow-case elements.

refer to their definition number.

Also: two small changes to flow graph printing.  Children of branch
nodes are visited in right-to-left order when performing depth first
search.  Instructions are numbered locally within blocks so as to not
destroy AST node number before printing (it's useful to print the
definition).

0143d707a6 Add an assigned variables analysis. 
This change adds a pass over the AST that computes the
set of assigned variables for locals and parameters for each expression.

The result of this analysis is used to for two purposes:
1. Recognize variables that are trivial subexpressions. A left sub-expression
   of a binary operation is trivial if it is a local variable or a parameter
   and it is not assigned in the right sub-expression. In the case of a 
   trivial left sub-expression we evaluate the right first.
   Currently only binary operations and compare operations are considered
   when finding trivial left sub-expressions.

2. Recogize certain simple for-loops with a constant trip count where the loop
   variable is always within smi range. If the loop count variable is not
   assigned in the body of the loop (except in the update expression the
   for-loop). This allows omitting smi checks on operation using the loop
   count variable.

504664365d Refactor the code cache to handle large number of properties on the global object (take 2). 
A separate object type for the code cache have been added. This object has two different code caches. The first one (default_cache) is a fixed array organized in the same way as the as the code cache was before. The second cache (global_access_cache) is for code stubs to access the global object. This cache is organized as a hash table taking the property name and code flags as the key.

The reason for separating the global access stubs into a hash table representation is that the number of these is not bounded in the same was as the other types.

This is a remake of r3952 (http://codereview.chromium.org/652119) which have the additional ability to look for the index of code stubs for access to the global object.

3817a7ba6e Small simplification of #include dependencies. 
Remove messages.h from v8.h and include it explicitly in only the few places
it is needed.  Many files relied on getting handles-inl.h implicitly from
messages.h through v8.h, so include handles-inl.h explicitly in v8.h
instead.

Remove zone-inl.h from header files where it is not needed, can be replaced
by a forward declaration, or can be replaced by zone.h (specifically,
factory.h and heap.h).  Include zone.h or zone-inl.h in header files where
it was implicitly included via heap.h or factory.h.  Prefer zone.h over
zone-inl.h in header files where possible by including zone-inl.h in .cc
files.

bce8d2ebae Remove unneeded variable usage analysis. 
A variable usage analysis pass was run on toplevel and lazily-compiled
code but never used.  Remove this pass and the data structures it
builds.

The representation of variable usage for Variables has been changed
from a struct containing a (weighted) count of reads and writes to a
simple flag.  VariableProxies are always used, as before.  The unused
"object uses" is removed.

8528d650d8 Initial implementation of an edge-labeled instruction flow graph. 
The flow graph is built by walking the AST.  Edges are labeled with
instructions (AST nodes).  Normal nodes have a single predecessor edge and a
single (labeled) successor edge.  Branch nodes are explicit, they have a
single predecessor edge and a pair of (unlabeled) successor edges.  Merge
nodes are explicit, they have a pair of predecessor edges and a single
(unlabeled) successor edge.

There is a distinguished (normal) entry node and a distinguished (special)
exit node with arbitrarily many predecessor edges and no successor edges.

The graph is intended to support graph-based analysis and transformation.

df4471c8f3 Fix stack tweaking in array allocation 
When Array(0) or new Array(0) is handled by the generated code it is handled
by the same code as Array() and new Array(). For this to work the stack is
tweaked to remove the argument of value 0. However the argc was still passed
as 1 if a call to the runtime system was made.

When the stack is tweaked argc is also changed to 0.

This is needed for my reimplementation of profiler tree generation in
C++. As generation is performed in a separate thread, Zone can't be
used, because it intentionally not thread-safe.

   FLAG_log (as it may be not enabled, e.g. in Chromium);

 - PauseProfiler / ResumeProfiler were supposing that they
   use 'is_logging_' var exclusively, thus preventing any

8398287070 Refactor the code cache to handle large number of properties on the global object. 
A separate object type for the code cache have been added. This object has two different code caches. The first one (default_cache) is a fixed array organized in the same way as the as the code cache was before. The second cache (global_access_cache) is for code stubs to access the global object. This cache is organized as a hash table taking the property name and code flags as the key.

The reason for separating the global access stubs into a hash table representation is that the number of these is not bounded in the same was as the other types.

Original review: http://codereview.chromium.org/646010/show

Change the implementation of lastIndexOf method of String. Convert the
strings in question to Vector<char> or Vector<uc16> and execute simple
search algorithm on them.

The difference in speed on 500k character string is about 10x.

a9202fc45d Begin using a list of bailouts instead of a singleton in the fast code generator. 
A list of bailout descriptions is kept in the CompilationInfo
structure that is shared between the primary and secondary code
generators.  The primary adds a description to the list for each
bailout position.

Responsibility for binding labels is moved from the primary to the
secondary code generator. All the labels still target the start of the
secondary code and the compilation state of the primary is still
ignored.

Move the compilation mode flag to the CompilationInfo.

ec86513519 Make class BitField able to use 32 bits of a uint32. 
Although algorithmically correct, the compiler would not allow to instantiate
a BitField that uses all 32 bits without warnings about a too large shift
count. As a consequence we were limited to 31 bit values when using BitField.

This happened when instantiating a bitfield BitField<T, shift, size> with 
[shift=0, size=32] or [shift=31, size=1] or more general any 
[shift=X, size=32-X]

As side-effect of the new implementation the compiler now warns if we ever
try instantiating a bitfield with size 0.

Add a (currently) syntactic predicate to AST expression nodes telling
whether they are 'trivial'.  Trivial expressions have no side effects,
do not require storage to be allocated for them, and can be evaluated
out of order (because their value does not change between when they
are visited by the code generator as expressions in the AST and when
it is consumed).

Mark 'this' and literals as trivial.  Allow them to be pushed on the
virtual frame.  Make use of them to push 'this' more lazily in this
property assignments.

Fix for issue 603.

Revision r3484 removed the property name from the call stack for
call ICs.  When a non-function was called via a call IC and
Function.prototype.call, an extra value was left on the stack that the
caller could not know to clean up.

Fix is to change the JS builtin used for calling non-functions.  It
now gets the callee as receiver, rather than iterating stack frames
and finding it on the expression stack of its JS caller.

ad9ea637be Don't externalize fresh strings. 
With the current API the embedder has to extrenalize a string each
time a string is encountered to avoid the cost of repeated character
copying/conversion. The issue here is that the externalization cost
itself is non-negligible (both in time and space) and should not be
paid for a rarely used string. This change is an attempt to predict a
string's usage frequency based on its freshness. A string is
considered fresh if it was recently allocated in the new space.

Also make the computation of the result type more precise and correct on both ia32 and x64.

dbe99e405a Introduce number type information in the virtual frame. 
Each frame element gets a new attribute with number type information. A frame element can be: 

- smi 
- heap number 
- number (i.e. either of the above) 
- or something else. 

The type information is propagated along with all virtual frame operations. 
Results popped from the frame carry the number information with them.

Two optimizations in the code generator make use of the new 
information: 
- GenericBinaryOpSyub omits map checks if input operands are numbers. 
- Boolean conversion for numbers: Emit inline code for converting a number (smi or heap number) to boolean. Do not emit call to ToBoolean stub in this case.

All two character string results from adding two strings and from sub string used to be handled in the runtime system as a lookup in the symbol table was done before allocating a new string. The native code for string add and sub string now probes the symbol cache for two character strings to avoid the runtime call. If the result string is not found in the symbol table within a fixed number of probes a new string is just allocated. Newly allocated two character strings are not added to the symbol table immediately.

4a2c81d3b0 Add last use data flow information to the fast code generator. 
This change add simple local live variable information to 
the fast code generator.  It supports only AST nodes that 
are accepted by the syntax checker.

Each variable use points to a variable definition structure
which contains the last use of the definition.

To determine whether a variable is live after a certain point
we can check whether its last use occurs later in the evaluation
order defined by the AST labeling number.

The new information is currently only printed out together with
the IR and not yet used for code generation.

Support a binary operation (bitwise OR) so long as it's not nested in
the left subexpression.  This ensures that the expression stack never
has height greater than two and so can be kept fully in registers.

The bounded expression stack height and the absence of any side
effects on the fast path allows us to still bailout out to the very
beginning of the function if any of our fast-path checks fail.

Added helper functions to the fast code generator for temporary, ad hoc
fixed register allocation.  Also inlined some helper functions that had only
one call site to simplify the code generator API for now.

2. Move functions register-allocator.h to the -inl.h file if they use other inline functions.
3. Add missing includes that resulted from the above changes.

2f0f6face1 Fast compiler: Load globals variables directly from property cells. 
This is a first step towards loading globals directly from property cells instead
of going through a load IC.

This change supports only properties with the DontDelete attribute since
we are only able to bailout into the generic code generated by the secondary 
code generator the beginning of a function. The resulting fast-case code is 
specialized for a specific context. When invoked with a different global object, 
it will always bailout to the secondary code.

When loading a property that does not exist at compile-time or a property
that is deleteable we still generate the generic load IC.

this causes the debug check to fails since type() asserts that the 
lookup_type != NOT_FOUND. This does not change any functionality since we 
explicitly checked if it was one of the three types that we need to delete.
Also changed defineProperties in v8natives to actually return the object

10910394e6 Handle insertion order for simple constructors 
When functions only have simple assignments of the form this.x = ... the object is created in generated code without actually calling the constructor. In this case the initial map for the function already contains the properties assigned in the constructor. The field descriptors in this initial map now has an enumeration index assigned to make property enumeration order the insertion order. The insertion order here is the order of the this.x assignments in the code.

048fe9b980 RFC: Try to be much more careful with where we skip the write barrier by: 
1. Avoid using SKIP_WRITE_BARRIER when we don't have to (smis).
  2. Check and document the remaining uses of SKIP_WRITE_BARRIER.
  3. Only allow GetWriteBarrierMode when in an AssertNoAllocation scope.

The only functional change should be in DeepCopyBoilerplate where we
no longer use the write barrier mode (because of allocations). I'm
running benchmarks to see if this has a measurable impact on performance.

97e3aae5ef Refactoring and small optimization of the smi code for binary op stubs 
on ia32.

1. Operate on the values in edx,eax when possible (all operations
except DIV and MOD).  This saves moving them on entry and when falling
out to the non-smi code.

2. Do not perform ADD and SUB before the smi check of their inputs.
This saves undoing the operation in the case that we fall through to
the non-smi case due to non-smi inputs (probably common?), and we can
avoid emitting the smi check code twice (code size reduction).

3. Don't perform OR twice (once to smi check the inputs and once to
smi check the result).

cf78ed05ee Don't pass the "at start" parameter to native RegExp 
As the start index is already passed it is easy to calculate the "at start" boolean in generated code. Also as direct entry has been implemented this needs to be done in generated code anyway, and therefore might as well be moved to the generated code for RegExp. The "at start" value is now calcualted as a local variable on the native RegExp frame based on the value of the start index argument.

The x64 version have been tested on both Linux and 64-bit Windows Vista.

For ARM I have tested cctest/test-regexp on ARM hardware, but the rest of the tests have only been run on the ARM simulator.

36477ee160 Use registers to pass arguments to GenericBinaryOpStub. 
Currently arguments are never passed on registers (due to the way ArgsInRegistersSupported is written) and
if they were, the stub would break in several places because registers are not preserved properly in the
course of execution. This CL makes use of registers more often (than never) and makes sure that registers are
handler properly.
A peformance gain is small (0.2-0.3%) but stable.
This CL was extracted from the one sent out earlier (http://codereview.chromium.org/551093).

We now test for a smi before calling ToNumber and inline
the smi increment/decrement for ++ and --. There only a small
increase in code size but loops in top-level code are
becoming much faster as a result.

40fd97c87d A follow-up to fix 553: really report function object moves. 
As an afterthought, I realized that I put function objects moves
reporting into a method that deals with only code object moves.  I've
looked up that function objects are allocated in old pointer space and
new space, so I moved logging to the corresponding VM methods.

999e3fca90 Fix issue 553: function frame is skipped in profile when compare stub is called. 
The problem appeared due to a fact that stubs doesn't create a stack
frame, reusing the stack frame of the caller function. When building
stack traces, the current function is retrieved from PC, and its
callees are retrieved by traversing the stack backwards. Thus, for
stubs, the stub itself was discovered via PC, and then stub's caller's
caller was retrieved from stack.

To fix this problem, a pointer to JSFunction object is now captured
from the topmost stack frame, and is saved into stack trace log
record. Then a simple heuristics is applied whether a referred
function should be added to decoded stack, or not, to avoid reporting
the same function twice (from PC and from the pointer.)

d587851d7f Fix map compact implementation. 
Always invoke HeapObjectIterator::has_next() before invoking HeapObjectIterator::next().
This is necessary as ::has_next() has an important side-effect of going to the next
page when current page is exhausted.

And to find if pointers are encodable use more precise data---top of map space, not a number
of pages, as pages might stay in map space due to chunking.

37d3972429 Fix issue 571: display descriptive names for code objects from snapshot. 
As this is only needed for internal profiling (not for DevTools),
the following approach had been chosen:

 - during snapshot creation, positions of serialized objects inside
   a snapshot are logged;

 - then during V8 initialization, positions of deserealized objects
   are logged;

 - those positions are used for retrieving code objects names from
   snapshot creation log, which needs to be supplied to tick processor
   script.

Positions logging is controlled with the new flag: --log_snapshot_positions.
This flag is turned off by default, and this adds no startup penalty.

To plug this fix to Golem, the following actions are needed:

 - logs created using 'mksnapshot' need to be stored along with VM images;

 - tick processor script needs to be run with '--snapshot-log=...' cmdline
   argument.

For IC calls to the V8 builtins values are not boxed and as most of the functions on String.prototype, Number.prototype and Boolean.prototype are sitting there most IC calls on values will not need any boxing of the receiver.

For calls which are not IC calls but calls through the CallFunctionStub a flag is used to determine whether the receiver might be a value and only when that is the case will the receiver be boxed.

No changtes to Function.call and Function.apply - they already boxed values. According to the ES5 spec the receiver should not be boxed for these functions, but current browsers have not adopted that change yet.

bd06358b93 Optimized calling of C++ builtins (and HandleApiCall 
in particular).

  * Called function is passed on the stack instead of
    using a static variable.

  * Builtins that don't need the called function don't
    get it.

  * Made is_construct statically known to HandleApiCall
    by setting custom construct stub for API functions.

acf74b04a7 Fix a problem when compiling built-ins with the top-level compiler. 
Replace runtime call to NumberAdd with call to binary op stub.

Until now the top-level compiler always called a runtime function
for count operations. 

In some places we expected in the JS builtins smis as arguments.
If we perform a count operation before all smis would get converted into
heap numbers by the runtime number add function and result in a runtime 
assert.

Also: Add missing debugger information in the top-level compiler for 
do-while loops.

903301248e Improve keyed loads on strings by using a new stub. 
Instead of going through a runtime function for keyed loads
on strings we invoke a separate specialized stub that
assumes string as receiver type and the key to be a number.

The stub calls a JS builtin function to return the corresponding one-character string.

Added a stub to allocate and fill a string object with a substring from another string.

Use the rep movs instruction to copy the string data as it turned out to be the fastest way.

While preparing this I experimented with some SSE2 instructions, so the instructions movdqa and movdqu are still in the IA-32 assembler even though they are not used.

429f3cf9f2 Direct call to native RegExp code from JavaScript. 
Calls to RegExp no longer have to be via a call to the runtime system. A new stub have been added which can handle this call in generated code. The stub checks all the parameters and creates RegExp entry frame in the same way as it is created by the runtime system. Bailout to the runtime system is done whenever an uncommon situation is encountered or when the static data used is not initialized. After running the native RegExp code the last match info is updated like in the runtime system.

Currently only ASCII strings are handled.

Added another argument to the RegExp entry frame. It indicated whether the call is direct from JavaScript code or through the runtime system. This information is used when RegExp execution is interrupted. If an interruption happens when RegExp code is called directly a retry is issued causing the interruption to be handled via the runtime system. The reason for this is that the direct call to RegExp code does not support garbage collection.

b74ab45077 Simplify checking during allocation when Heap::always_allocate() is 
true.  The rules are:

1. Heap::AllocateRaw can normally handle allocation requests in new
   space even when always_allocate() is true.  It properly retries
   failed allocation in the second 'retry' space.

2. Heap::Allocate can normally handle allocation requests in new
   space.

3. We only need to check always_allocate() when explicitly requesting
   allocation in new space via Heap::new_space().AllocateRaw().

4. The exception to these rules is fixed arrays with size such that
   MaxObjectSizeInPagedSpace < size <= MaxObjectSizeInNewSpace (ie,
   those that will be allocated in new space and promoted to large
   object space).  They cannot be allocated in new space via
   Heap::Allocate or Heap::AllocateRaw, because the retry logic does
   not know to allocate extra remembered set bits when retrying in
   large object space.

0553c7feb9 Optimize bitops with non-Smi inputs. Instead of converting both inputs 
to floating point and then converting back we convert directly to a
32 bit integer.  In addition the bit twiddling implementation of float-
to-integer conversion has been ported from ARM.  Testing has shown that
this runs faster than the x87 or SSE3 rounding instructions.  This change
is IA32 only.  There may be a smaller benefit from doing the same on x64.

44b7c59eb5 Extend the maximum size map space 
On 32-bit the maps are now aligned on a 32-byte boundary in order to encode more maps during compacting GC. The actual size of a map on 32-bit is 28 bytes making this change waste 4 bytes per map.

On 64-bit the encoding for compacting GC is now using more than 32-bits and the maps here are still pointer size aligned. The actual size of a map on 64-bit is 48 bytes and this change does not intruduce any waste.

My choice of 16 bits for kMapPageIndexBits for 64-bit should give the same maximum number of pages (8K) for map space. As maps on 64-bit are larger than on 32-bit the total number of maps on 64-bit will be smaller than on 32-bit. We could consider raising this to 17 or 18.

I moved the kPageSizeBits to globals.h as the calculation of the encoding really depended on this.

There are still an #ifdef/#endif in objects.h and this constant could be moved to globaks.h as well, but I kept it together with the related constants.

All the tests run in debug mode with additional options --gc-global --always-compact as well (except for a few tests on which also fails before this change when run with --gc-global --always-compact).

0672938b88 Fix a crash caused by garbage collection during generation of a 
callback load (or keyed load) IC.

The problem was that the IC code calls a stub, which can allocate and
thus trigger a GC if the stub is not already generated.  Problem is
solved by adding the ability to "try" to call a stub, trying to
generate the stub code if necessary but signaling an allocation
failure if generating the code is not possible.
