Fix reintroduction of global variables that have been deleted.
...
Deletion of global properties puts 'the hole' in the global property
cell and updates the property details in the property dictionary with
the information that the property has been deleted. When setting
global properties that have been deleted in generated code we just
store the new value in the global property cell. This does not update
the property details in the property dictionary. Therefore, it looks
like the property is not there eventhough it was just reintroduced.
Perform 'the hole' checks in generated code for global property stores
and bail out of ICs and optimized code if storing to a property cell
that contains 'the hole'.

Truncate rather than round to nearest when performing float-to-integer
...
conversions for external array types, which implement the Typed Array
spec. (Revision of http://codereview.chromium.org/6315004 .)
Prefer SSE2 code path on x86 processors. Non-SSE2 processors now make
a slow runtime call for float-to-int conversions. Use SSE3 for 32-bit
signed and unsigned int array types where possible.
The movement of code from ic-arm.cc to stub-cache-arm.cc caused the
VFP3 code path to be tested for the first time. Fixed bugs in the
register usage and in the constant value stored into integer arrays
for NaN and +/-Infinity.
Added new truncation test to test-api.cc. Storage of NaN and +/-Inf
was already covered. Ran unit tests on x86, x64 and ARM simulator.
Tested ia32 and x64 code in Chromium on Mac and Linux respectively
with Typed Array unit tests and WebGL content.

Truncate rather than round to nearest when performing float-to-integer
...
conversions for external array types, which implement the Typed Array
spec. The new code paths are for SSE3 and SSE2 capable processors.
The code for non-SSE2 processors is unchanged for now. The ARM port
appears to already be correct.
Moved the generation of the external array load and store intrinsics
to the stub cache (on all platforms) so that they are generated at run
time and can take advantage of CPU features.
This functionality is covered by the array-unit-tests.html test in the
WebGL conformance test suite:
http://khronos.org/webgl/wiki/Testing/Conformance
https://cvs.khronos.org/svn/repos/registry/trunk/public/webgl/sdk/tests/conformance/array-unit-tests.html

Extra IC state is only two bits and only supported for call IC-s for

Fix crashes during GC caused by partially initialized objects. The

inline allocation code used the expected number of properties to
calculate the number of inobject properties for an object instead of
getting the actual number from the initial map.
It is safer to use the inobject property count from the initial map in
any case because that is the amount the instances will get. I think
this disconnect got introduced when adding shrinking of objects.
Unfortuntely I haven't been able to create a simple reproduction for a
test case but this fixes the webpage that exhibits the crash. I'll see
if I can create a reproduction tomorrow.
