As proposed in https://github.com/WebAssembly/simd/pull/122. Since
these instructions are not yet merged to the SIMD spec proposal, this
patch makes them entirely opt-in by surfacing them only through LLVM
intrinsics and clang builtins. If these instructions are made
official, these intrinsics and builtins should be replaced with simple
instruction patterns.
