Lang Hames 23de211c5d Replace vfmaddxx213 instructions with their 231-type equivalents in accumulator 
loops. Writing back to the accumulator (231-type) allows the coalescer to
eliminate an extra copy.

Cameron Zwarich f03fa189ca Add an intrinsic and codegen support for fused multiply-accumulate. The intent 
is to use this for architectures that have a native FMA instruction.
