As the list of code-stubs is used in two places it is now handled through a macro to keep this in sync. As some code-stubs is only used on ARM the list have been split into two parts to indicate this and get rid of dummy implementation on ia32 and x64 platforms.

The alignment of new space has to match the alignment in the snapshot,
but the max committed amount of memory does not.

For now, we assume that the default semispace size is always used in a
snapshot.

specification under development. The optimizations are patterned after
those previously done for CanvasPixelArray. This CL adds all of the
necessary framework but continues to use the generic KeyedLoadIC and
KeyedStoreIC code, to create a baseline for benchmarking purposes. The
next CL will add the optimized ICs to ic-ia32.cc and ic-x64.cc.

These new CanvasArray types have different semantics than
CanvasPixelArray; out-of-range values are clamped via C cast
semantics, which is cheaper than the clamping behavior specified by
CanvasPixelArray. Out-of-range indices raise exceptions instead of
being silently ignored.

As part of this work, pulled FloatingPointHelper::AllocateHeapNumber
up to MacroAssembler on ia32 and x64 platforms. Slightly refactored
KeyedLoadIC and KeyedStoreIC. Fixed encoding for fistp_d on x64 and
added a few more instructions that are needed for the new ICs. The
test cases in test-api.cc have been verified by hand to exercise all
of the generated code paths in the forthcoming specialized ICs.

Turned on with '--log-producers' flag, also needs '--noinline-new' (this is temporarily), '--log-code', '--log-gc'. Not all allocations are traced (I'm investigating.)

Stacks are stored using weak handles. Thus, when an object is collected, its allocation stack is deleted.

The profile is taken together with constructors profile. In theory, it
should represent a complete heap graph. However, this takes a lot of memory,
so it is reduced to a more compact, but still useful form. Namely:

 - objects are aggregated by their constructors, except for Array and Object
   instances, that are too hetereogeneous;

 - for Arrays and Objects, initially every instance is concerned, but then
   they are grouped together based on their retainer graph paths similarity (e.g.
   if two objects has the same retainer, they are considered equal);

Also:
- move constructor name getter near similar class name getter method;
- if the constructor is not present, use 'Object', as for class name, this eliminates a special case.

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.

Android system provides a unique feature that it sends a notification to the
browser in low memory condition, and the browser cleans up cache and frees
resources. Forcing a GC in low memory condition can free DOM objects and also
can shrink the old spaces.
