Define x86 fused multiply-add intrinsics
This defines the following intrinsics for 128 and 256 bit vectors of f32 and f64: * `fmadd` * `fmaddsub` * `fmsub` * `fmsubadd` * `fnmadd` * `fnmsub` The `_sd` and `_ss` variants are not included yet. Intel intrinsic reference: https://software.intel.com/en-us/node/523929 The intrinsics there are listed under AVX2, but in the Intel Intrinsic Guide they are part of the "FMA" technology, and LLVM puts them under FMA, not AVX2.
