We were emitting the wrong instructions for fused multiply-add
operations on LLVM:
- the instruction name is "llvm.fma.f32" or "llvm.fma.f64", not "fmadd"
- LLVM does not support other instructions such as "fmsub"; instead
we implement these by flipping signs of some arguments
- the instruction is an LLVM intrinsic, which requires handling it
like a normal function call instead of a machine instruction
