3d7ce8ac19 CPU profiler: add secure profiles by filtering out functions using security tokens. 
As several pages can run in a single V8 instance, it is possible to
have functions from different security contexts intermixed in a single
CPU profile.  To avoid exposing function names from one page to
another, filtering is introduced.

The basic idea is that instead of capturing return addresses from
stack, we're now capturing JSFunction addresses (as we anyway work
only with JS stack frames.)  Each JSFunction can reach out for
context's security token. When providing a profile to a page, the
profile is filtered using the security token of caller page. Any
functions with different security tokens are filtered out (yes, we
only do fast path check for now) and their ticks are attributed to
their parents.

d25c36deee ARM: Pass arguments to keyed store IC in registers 
The calling convention for keyed store IC on ARM is changed to receive the arguments value, key and receiver in registers r0, r1 and r2 instead of on the stack. When calling keyed store IC with a virtual frame the arguments are passed through the virtual frame and consumed by the call.

Changed the register usage in the IC code to postpone spilling the registers holding value, key and receiver to the stack until making  a call into the runtime system.

Runs all the tests with: 

  --special-command="@ --nofull-compiler"
  --special-command="@ --always-full-compiler"
  --special-command="@ --noenable-vfp3"

02ca5fd8b2 ARM: Fix generating two ldr instructions in place of ldrd. 
When ldrd is not available two ldr instructions are generated. This fixes these in the case where the register used in the memory operand is the same as the first register in the register pair receiving the values.

All tests now run on ARM with the flag --special-command="@ --noenable-vfp3". Running without VFP3 support in the simulator causes more ldrd instructions to be used, and the default build configuration does not utilize ldrd, but generated tow ldr instructions.

e9b5d7855b Allow build-time selection between ia32 and x86_64 in the GYP/Xcode Mac 
Chromium build.

v8.gyp no longer sets any V8_TARGET_ARCH_* macro on the Mac. Instead, the
proper V8_TARGET_ARCH_* macro will be set by src/globals.h in the same way as
the V8_HOST_ARCH_* macro when it detects that no target macro is currently
defined. The Mac build will attempt to compile all ia32 and x86_64 .cc files.
#ifdef guards in each of these target-specific source files prevent their
compilation when the associated target is not selected. For completeness,
these #ifdef guards are also provided for the arm and mips .cc files.

6046ae7bcd Fix dtoa for the LP64 model on 64-bit systems, where long is 64 bits. 
dtoa.c:69 states: #define Long int on machines with 32-bit ints and 64-bit
longs. This change was made in Chromium's version of dtoa in r21901. I don't
know why this apparently hasn't caused a problem in v8 until now. I was
unable to build a snapshot on x86_64 Mac without this change.

c7b2af37ba Use direct loop when filling small arrays. 
r3995 (http://code.google.com/p/v8/source/detail?r=3995) introduce performance
regression for the case when arrat size is small (think new Array(4)).

It turns out that in those cases rep stos is slower than plain loop (apprently
due to ecx increment, but I didn't check this hypothesis.)  The next thing
to try could be direct jump into right place of long sequence of stos'es.

fa7c92eaf5 First step towards making JumpTarget work on ARM. Instead 
of having a list of virtual frame pointers in the jump
target we have one virtual frame, which is the frame that
all have to merge to to branch to that frame.  The virtual
frame in the JumpTarget is inside the JumpTarget, rather than
being an allocated object that is pointed to.  Unfortunately
this means that the JumpTarget class has to be able to see
the size of a VirtualFrame object to compile, which in turn
lead to a major reorganization of related .h files.  The
actual change of functionality in this change is intended
to be minimal (we now assert that the virtual frames match
when using JumpTarget instead of just assuming that they do).

8d51195778 Fixed issue 619 allowing Object.create to be called with a function. 
This change allows Object.create to take a function as input in the
proto argument. The spec says that Type(O) for the proto argument
should be true but our IS_OBJECT does not check for this. I will make a
IS_SPEC_OBJECT in macros.py and refactor v8natives in another CL.

fb3e01a306 Correct issue 696 with Date.parse returning a value when called on a non date string. 
The error was introduced in revision 4557 where support was added for
ES5 date time format strings. Because there was no check for a valid
year a random string starting with a non-digit character would be
parsed.

This change disallows ES5 formatted dates where there is no date
fraction (i.e., with only a timestamp). Since none of the other
browsers support Date.parse on only timestamps I have disabled this
totally instead of just correcting the parser.

The calling convention for keyed load IC's on ARM now passes the key and receiver in registers r0 and r1.

This is mainly a port of r3899. It also adds handling of initilization blocks in ARM which had no special handling before.

The "calling conventions" used for

  EmitNamedLoad
  EmitNamedStore
  EmitKeyedLoad
  EmitKeyedStore

daf1ea3970 Avoid constant pool blocking for too long 
The generation of the deferred code for named property load where the load was inlined did a constant pool blocking for the whole deferred code. Having large numbers of this type of deferred code generated one ofter the other effectively blocked the constant pool for all the deferred code causing 

Removed the BeforeGenerate/AfterGenerate for the deferred code and made macro assembler StartBlockConstPool/EndBlockConstPool non-public. Re-introduced BlockConstPoolFor instead to use with BlockConstPoolScope to block some more instructions cross function calls.

Also handle the use of native code counters for inlined named property load.

  export GYP_DEFINES="target_arch=ia32 v8_target_arch=arm"

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).

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.

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.

5423170113 Tweak D8 remote debugger 
When D8 is used as remote debugger the command 'break' (shorthand 'b') can be used to break JavaScript execution.

Fixed the printing of the prompt 'dbg>' and printing of error messages.

324eee1f3f Only put VM state entry if a symbolized stacktrace is empty. 
This makes more sense than putting "(program)" as the root of
every stack trace in broswer mode.

61085478c6 Report approximated duration in milliseconds for profile nodes. 
The simple formula "ms = ticks * sampler_interval" doesn't work,
because e.g. on Linux, the actual sampling rate can be 5 times
lower than the one set up in the code. To calculate actual sampling
rate, current time is periodically queried and processed along with
actual sampling ticks count.

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.
