These instructions previously used prefixes like v8x16 to signify that they were agnostic between float and int interpretations. We renamed these instructions to remove this form of prefix in https://github.com/WebAssembly/simd/issues/297 and https://github.com/WebAssembly/simd/issues/316 and this commit brings the names in LLVM up to date.
