When lowering fadd/fsub/fmul(a, select(mask, b, splat(0))) the sel
instruction can be removed by using predicated add/sub instructions.

Also adds patterns for:

  fadd(a, select(mask, fmul(b, c), splat(0))) -> fmla(a, mask, b, c)
  fsub(a, select(mask, fmul(b, c), splat(0))) -> fmls(a, mask, b, c)
