Ng Zhi An 19be491388 [wasm-simd] Optimize codegen when shift is constant ... Define a macro in code-generator-x64 to help identify cases when the shift value is an immediate/constant. In those cases we can directly emit the shifts without any masking, since the instruction selector would have modulo-ed the shift value. We also don't need any temporaries in this case. This is only x64 codegen, optimizations for other archs will come in future patches (and will probably look very similar to this). The current test case passes the shifts as an immediate, so we add a new path that loads the shift value from memory, thereby exercising the slower path of non-immediate shift value.
