[WebAssembly] Add SIMD QFMA/QFMS

Authored by tlively on Aug 30 2019, 2:21 PM.



Adds clang builtins and LLVM intrinsics for these experimental

They need benchmarking data before they can be merged into the proposal, and they need to be supported in the toolchain for us to get good benchmarking data.
