895f1d22e5 Implemented specialized stubs for API getters. This includes a number
of individual changes:

  - Added infrastructure for custom stub caching.
  - Push the code object onto the stack in exit calls instead of a
    debug/non-debug marker.
  - Remove the DEBUG_EXIT frame type.
  - Add a new exit stub generator for API getters.

ef95097334 Stop throwing exceptions for out-of-range accesses to CanvasArrays.
This is per resolution in the WebGL working group to make these types
match the WebIDL IndexSetter and IndexGetter semantics, which are
still being defined but will very likely not throw.

d5f00cf6cc Add optimized ICs for new CanvasArray types introduced in WebGL
specification under development. This is a follow-on CL to
http://codereview.chromium.org/293023 .

Based on review feedback, defined the behavior of storing NaN and
+/-Infinity into external arrays of integer types as storing 0. Added
test cases. Added fucomi instruction to assembler. Fixed bug in
KeyedLoadIC::GenerateExternalArray when allocation of HeapNumber
failed. Fixed bug in encoding of 16-bit immediate arithmetic
instructions in 64-bit port.

Removed raising of exceptions for negative array indices passed to
external arrays and associated tests. Based on current discussion in
WebGL working group, will probably end up removing the exception
throwing altogether.

kbr@chromium.org
46e6297e3e Added infrastructure for optimizing new CanvasArray types in WebGL
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.

b95dbc3fdd Make global variable initialization consistent with Firefox and Safari
behavior.  Only force the introduction of a variable directly on the
global object if there is an explicit initial value in a variable
declaration.

92bb897081 Tweaks to global object inline cache code.
Remove the check for deleted properties in the global load inline cache if the property is known to be read only.

Propegate the in loop flag for the global call inline cache.

Changed the propagation of the code flags in the call stub compiler to compute these the same way for all types of call stubs and assert that the flags for the generated code is the same as those used for the cache lookup.

Addressed a few comments from previous review in test-api.cc.

a54a4ada5c Changed the global object representation.The global object is now always in dictionary (slow) mode with each of its properties stored in a cell object. A cell object has one field containing the actual value for the property. Inline caches for access to global properties which uses direct to the cell are now created for load, store and call to properties of the global object. When properties of the global object are deleted the cell for that property is kept with an indcation of that the property is deleted.Added counters to track the use of the global property inline caches.Added additional information on IC's in the disassembler.
