Fixed unsafe code where a GC could occour after a Handle had been deferenced.
...
instances->set(i, *GetScriptWrapper(script));
GetScriptWrapper can call GC. The failure have only been seen on ARM, where
the g++ compiler pulls out the object from the instances handle to a register
before calling GetScriptWrapper causing set to be called on an object which
may have moved.
Marked a test on ARM as no longer flaky, whereas two other fails consistently
but that is no longer related to the problem fixed above.

- Added a map cache for literal objects. This will
...
canonicalize maps for object literals. JSON objects
with the same set of properties names will then
share the same map.
This reduces the amount of generated code associated
with object literals.
- Added a flag canonicalize_object_literal_maps.
(default true)
- Changed the format of a function's literal array.
Only the global context is now stored in the literal prefix.

on a line of its own. This allows the body to be terminated by a

Also, make sure to set the name of the function to anonymous after the
fact so that recursion through the name anonymous is not allowed and

Defer the writing of the source position data to the relocation information
...
until a possible debug break location is reached. Currently this is call sites
with calls to code objects and JS return. Source position information in the
code therefore no longer refers to the "first" instruction generated for a
given source position (which was not the case defered code anyway) but to the
first break location after that source position was passed (again defered code
always start with source position information). This doesn't make a difference
for the debugger as it will always be stopped only at debug break locations.
However, this makes the life of the peep-hole optimizer much easier as many
oportunities for posh/pop eliminations where previosly blocked by relocation
information already written to the code object.
Two types of source positions are still collected. Statement positions indicate
the position of the start of the statement leading to this code and (plain)
positions indicate other places typically call sites to help indicate current
position in backtraces. The two different types of positions are also used to
distinguish between step next and step in.
Runs all the tests (including debugger tests) as before.
Moved the checking for the FLAG_debug_info to one place.
I will do the same changes to the ARM codegenerator in a seperate changelist.

This is a new static flag system, designed to have all flags in a central place, and compiled into the binary without requiring static constructors for registration. All flags are moved out of the specific modules and into flags.defs, with different sections for debug, release, etc. The flag variables are always defined. For example, a debug flag in release mode still exists, but is read only and set to the default value.

Adapt to new calling convention on ARM:
...
- Simplified frame entry and frame exit code.
- Added ArgumentsAdaptorTrampoline and check for matching argument counts in the InvokePrologue.
- Removed definition and uses of USE_OLD_CALLING_CONVENTIONS.
- Changed MacroAssembler::InvokeBuiltin to match ia32 version.
- Start introducing convenience instructions in the ARM assembler as needed. These instructions take all Register parameters to avoid extra typing of "Operand(reg)".
To keep the architectures in sync these changes have been made to the ia32 files:
- Changed MacroAssembler::EnterFrame(StackFrame::Type type) to MacroAssembler::EnterInternalFrame().
These parts are still missing:
- unimplemented: Builtins::Generate_FunctionApply - large limit
- unimplemented: Builtins::Generate_ArgumentsAdaptorTrampoline - non-function call
- The files have not been lint'd yet.

Generalized the EvalCache into a CompilationCache and enabled

it for scripts too. In the context of Chromium, this should
have a very positive impact on memory consumption for web apps
that run multiple tabs from the same domain with a lot of the
same JavaScript code.
For now, the cache retirement policy is really simple:
Whenever a mark-sweep collection is started we clear the
cache. This guarantees that this change will not have a
huge negative impact on memory consumption, but it may
not be ideal. We should consider a more sophisticated LRU
scheme.

It turned out that the stack overflow fix from before had disabled
message storing in another test. Previously, stack overflows would
actually cause a message object to start being created but cause
another exception which would not be reported and that's what stopped
the infinite regress. This change resores that behavior.

__ push(eax);

__ push(eax) must happen before RecordWrite because RecordWrite may destroy

This only affects the case where a context variable is used in a inner scope.
Create a tests for it. It fails if __ push(eax) is after RecordWrite.

Removed the implicit call to DebugBreak when receiving debugger commands
...
while V8 is running.
A debugger using the V8 message based interface now needs to control the
call to DebugBreak in order for the messages send to be processed. Commands can
still be send when V8 is not in a break, but they will not be processed until
there is a break. The response "request queued" when queuing up messages have
been removed. This gets rid of a non JSON message being used.
Modified the threaded debugger tests to call DebugBreak instead of relying
on it occouring automatically.
This change will not be committed until the outstanding Chrome change
http://chrome-reviews.prom.corp.google.com/2072 (which updates Chrome to control
the DebugBreak call) have been reviewed and committed.

In the shell sample don't print the result of executing a script, only

Fixed issue when building samples on Windows using a shared V8
library. Added visibility option on Linux build which makes the
generated library 18% smaller.
Changed build system to accept multiple build modes in one build and
generate seperate objects, libraries and executables for each mode.
Removed deferred negation optimization (a * -b => -(a * b)) since this
visibly changes operand conversion order.
Improved parsing performance by introducing stack guard in preparsing.
Without a stack guard preparsing always bails out with stack overflow.

Added source for lazily loaded scripts to snapshots and made serialization non-destructive.
Improved ARM support by fixing the write barrier code to use aligned loads and stores and by removing premature locals optimization that relied on broken support for callee-saved registers (removed).
Refactored the code for marking live objects during garbage collection and the code for allocating objects in paged spaces. Introduced an abstraction for the map word of a heap-allocated object and changed the memory allocator to allocate executable memory only for spaces that may contain code objects.
Moved StringBuilder to utils.h and ScopedLock to platform.h, where they can be used by debugging and logging modules. Added thread-safe message queues for dealing with debugger events.
Fixed the source code reported by toString for certain builtin empty functions and made sure that the prototype property of a function is enumerable.
Improved performance of converting values to condition flags in generated code.
Merged disassembler-{arch} files.
