Introduce Float32x4, Int32x4, Float32x4Array and Int32x4Array data
types, implement the SIMD operations on the Float32x4 and Int32x4 with
C++ runtime functions and implement Float32x4Array and Int32x4Array
element loading and storing.
Optimize Float32x4Array and Int32x4Array element loading and storing for
ia32 and x64 port by:
  1). Allocating SIMD128 registers
  2). Emitting SIMD movups instruction
  3). Adding deoptimization support for SIMD128 registers or stack slots
Inline all SIMD operations and emit SIMD instructions for ia32 and x64 port
Initialize fixed Float32x4 and Int32x4 array elements properly.

This commit should be squashed with the previous commit.
Fix shufps encoding error for x64 port

This should be squashed with previous commits.
Implement builtin operators for Float32x4 and Int32x4
Update ToBooleanStub to support Float32x4 and Int32x4
