    [wasm-simd] Share i8x16.swizzle implementation · f70cfb88

    Also move Pshufb definition into shared-macro-assembler. We define a
    Pshufb that handles both SSE and AVX, and in SSE case will move src to
    dst if they are not the same.
    
    Define operator== and operator!= in ia32's Operand class that will check
    against XMMRegister, we can then use DCHECK_NE to ensure that a register
    doesn't alias a operand wrapping a register.
