Kicks off the implementation of wasm SIMD128 support (spec: https://github.com/stoklund/portable-simd/blob/master/portable-simd.md), adding support for add, sub, mul for i8x16, i16x8, i32x4, and f32x4. The spec is WIP, and might change in the near future. Patch by João Porto Differential Revision: https://reviews.llvm.org/D22686 llvm-svn: 277543
