kbr@chromium.org cbc1c0fca6 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.
