Added a simple new space check on the elements fixed array which can allow

Also combined the positive smi and range check so that a separate smi check can be avoided when the key is known to be a smi.

Introduce number type information in the virtual frame.
...
Each frame element gets a new attribute with number type information. A frame element can be:
- smi
- heap number
- number (i.e. either of the above)
- or something else.
The type information is propagated along with all virtual frame operations.
Results popped from the frame carry the number information with them.
Two optimizations in the code generator make use of the new
information:
- GenericBinaryOpSyub omits map checks if input operands are numbers.
- Boolean conversion for numbers: Emit inline code for converting a number (smi or heap number) to boolean. Do not emit call to ToBoolean stub in this case.

Fast compiler: Load globals variables directly from property cells.
...
This is a first step towards loading globals directly from property cells instead
of going through a load IC.
This change supports only properties with the DontDelete attribute since
we are only able to bailout into the generic code generated by the secondary
code generator the beginning of a function. The resulting fast-case code is
specialized for a specific context. When invoked with a different global object,
it will always bailout to the secondary code.
When loading a property that does not exist at compile-time or a property
that is deleteable we still generate the generic load IC.

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.
