As specified in https://github.com/WebAssembly/simd/pull/232. These
instructions are implemented as LLVM intrinsics for now rather than
normal ISel patterns to make these instructions opt-in. Once the
instructions are merged to the spec proposal, the intrinsics will be
replaced with proper ISel patterns.
