FMA_EXPR is created though not only just for __builtin_fma{,l,f} in the code,
but also for x * y + z when contracting.  Can expansion rely that this is
happening only after IPA passes?  Otherwise we could be creating fma,f,l} calls
in freestanding environments, or try create it say for __float128 where there
is no such builtin, etc.
