62e9956c91 Move object allocation in new space to macro assembler 
Currently allocation in generated code on ARM is only used for allocating heap numbers. This change factors this out for use in upcomming changes.

369214c159 Use a root array register for constant loads and stack guards on x64. 
This only wins us around 1% in performance, but it makes the code more
compact.  We don't currently have a way to represent in the virtual
frame that a slot contains a value from the root array.  Adding this
would probably make the code more compact.

This is change is identical to http://codereview.chromium.org/174524 (committed in r2768 and reverted in r2769) except that line 710 in macro-assembler-ia32.cc is

  cmp(result_end, Operand::StaticVariable(new_space_allocation_limit));

instead of

  cmp(result, Operand::StaticVariable(new_space_allocation_limit));

717394492d Generate specialized constructor code for constructing simple objects. 
For objects which only have simple assignments of the form this.x = ...; a
specialized constructor stub is now generated. This generated code allocates the
object and fills in the initial properties directly. If this fails for some
reason code continues in the generic constructor stub which in turn might pass
control to the runtime system.

Added counter to see how many objects are constructed using a specialized stub.

The specialized stub is only implemented for ia32 architecture in this change.
For x64 and ARM the generic construct stub is used.

This is change is identical to http://codereview.chromium.org/174392 (committed in r2753 and reverted in r2754) except that a few parts have already been committed from http://codereview.chromium.org/173469 (committed in r2762).

681440e273 Handle pre-allocated properties when copying map. 
When copying a map always set the descriptor array to describe the pre-allocated properties, even when descriptors are to be dropped.

Added a test which otherwise failed with an assert on ARM in debug mode. The reason for it only surfasing on ARM is that the NewObject runtime function is always used for allocating new JSObjects on ARM.

This change includes a few parts of http://codereview.chromium.org/174392 needed to trigger the error.

resources. Forcing a GC in low memory condition can free DOM objects and also
can shrink the old spaces.

Make sure that the DummyScope top level scope used for pre-parsing have all members initialized. The type of this scope is set to global scope as it is a top level scope. Also ensure that the "naked" Scope constructor can only be used by sub-classes of Scope.

4e03645dc4 Analyze functions for assignment to this properties. 
During parsing functions are analyzed for statements of the form this.x = ...;. These assignments are categorized in two types: simple and non simple. The simple ones are where the right hand side is known to be either a constant or an argument to the function. If a function only contains statements of this type the property names are collected and for the simple assignments the index of the argument or the constant value assigned are stored as well.

When the initial map for a function is created and the function consists of only this type of assignemnts the initial map is created with a descriptor array describing these properties which will be known to always exist in an object created from the function.

The information on this property assignments is not collected during pre-parsing so if compiling using pre-parse data these optimization hints are not available.

Next step will be to use the information collected for the simple assignments to generate constructor code which will create and initialize the object from this information without calling the code for the function.

f39651cbcd Land change to notify valgrind when we modify code on x86. This does 
not seem to impact performance and makes it a lot easier for people
embedding V8 to run their application under valgrind.

If we observe a negative performance impact, we will need to revise
this again.

9edc69c72f Add support for (some) assignment expressions to the CFG builder and 
fast-mode compiler.

1. We avoid generating a useless temporary for assignments with
nontrivial right-hand sides.  Instead of translating id = expr into:

...
tmp = <last expr instruction>
id = tmp

we generate directly

...
id = <last expr instruction>

by passing a data destination ('hint') down the AST.  The semantics is
to use the destination as a result location if a temp is needed.  It
may be ignored.  NULL indicates I don't care and you should generate a
temp.

2. We correctly handle assignments as subexpressions.  When building
the CFG for an expression we accumulate the assigned variables and we
emit a move to a fresh temporary if a value in a variable is in
jeopardy of being overwritten.

5470f9b132 Add an ability to initiate GC through V8 API. 
I'm planning to use it in DevTools heap profiler. It is a common scenario in debugging memory leaks to enforce GC, then perform an operation, then enforce GC again to check for non-collected (that is, leaked) objects. Using the existing GC extension isn't possible because it doesn't exposed in the normal operation mode of Chromium.

3d070f1f0c - Fix a style violation which was flagged by gcc: while loop without body 
- Restructured the entire function because:
  During the simple style fix I discovered that this whole routine was
  hard to read due to a general lack of comments. While adding comments I
  realized that the function was also skipping entries if there were two
  consecutive entries in the maps file.

cffc051177 Avoid dictionary expansion during bootstrapping. 
Allocate the code stubs dictionary and non monomorphic cache dictionary with an initial size which avoids these dictionaries to be expanded during bootstrapping. This gets rid of 9 dictionary expansions during bootstrapping.

Preallocate the dictionary when normalizing an object to a size sufficient for holding the number of properties which is expected to be added to the object. This is used when ceating an object from an object literal boilerplate where multiple properties are known to be added.  This gets rid of 10 dictionary expansions during bootstrapping.

There are now 3 dictionary expansions left during bootstrapping.

98425a31f1 Speed up CalledAsConstructor. 
Changed CalledAsConstructor to process the raw runtime stack directly,
rather than using a StackFrameIterator.  Using an interator turns out
to be quite expensive and the vast majority of the work done is not
relevant to deciding if we've been called as a constructor.

This speeds up getElementById by ~13%.

e97554ed10 Add generic V8 API functions for controlling profiling aspects. 
As we'll have several aspects of heap profiling, it is more handy to control them using binary flags than by individual functions. CPU profiling represent just a particular aspect to control, so {Pause,Resume}Profiler and IsProfilerPaused are only left for compatibility.

For now, PROFILER_FLAG_HEAP_STATS and PROFILER_FLAG_JS_CONSTRUCTOR are equivalent, but later will be split.

9e8216ef22 Introduce first approximation of constructor heap profile for JS objects. 
It is activated with '--log-gc' flag.

JS object size is calculated as its size + size of 'properties' and 'elements' arrays, if they are non-empty. This doesn't take maps, strings, heap numbers, and other shared objects into account.

As Soeren suggested, I've moved ZoneSplayTree from jsregexp to zone, and removed now empty jsregexp-inl header file.

161d38c614 Debugger should not stop in its own code and in code of built-in functions since it may confuse user.Debug break handler checks whether current function is a built-in or a debugger one and just resumes execution if it is. 
CallCheckStackGuardState is no longer called in loop in the RegExp code as it hangs if debug break flag is not reset after calling Execution::HandleStackGuardInterrupt.

4196711d2e Call the (fatal) V8 out of memory handler if we cannot allocate enough 
memory from the OS to deserialize the initial heap snapshot at
startup.

This catches the failure to startup earlier, and avoids dereferencing
the encoding of an allocation failure.

1ca19c383d Fix ARM compiler crash in short-circuited boolean expressions. 
We did not handle the case where the left-hand-side expression was
fully compiled to control flow.  There were also some assertions for
unary and binary expressions that crashed debug builds when the
expression was fully compiled to control flow.

Regression test added.

e8ae83eec3 Remove a few occurrences of the CHECK_FAILED macro in the parser. 
There's no reason to check if we've failed when (a) we know we have
and (b) we've got a perfectly good NULL just lying around anyway.
