With LTO, relying on FMA_EXPR being present in the IL only iff target supports
it is IMHO wrong, because using slightly different options between cc1 and lto1
can result in optab_handler (fma_optab, mode) == CODE_FOR_nothing even when
FMA_EXPR is present in the IL. I'd say we should expand FMA_EXPR as
__builtin_fma in that case. Richi, do you agree?
