Make CanDeoptimize() check of kStoreKeyed depend on elements_kind.

If the elements_kind is SIMD128, kStoreKeyed can deoptimized.
Optimize Float32x4Array, Float64x2Array 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
