PR target/54564
* config/i386/sse.md (fmai_vmfmadd_<mode>): Use (match_dup 1)
instead of (match_dup 0) as second argument to vec_merge.
(*fmai_fmadd_<mode>, *fmai_fmsub_<mode>): Likewise.
Remove third alternative.
(*fmai_fnmadd_<mode>, *fmai_fnmsub_<mode>): Likewise. Negate
operand 2 instead of operand 1, but put it as first argument
of fma.
* config/i386/fmaintrin.h (_mm_fnmadd_sd, _mm_fnmadd_ss,
_mm_fnmsub_sd, _mm_fnmsub_ss): Negate the second argument instead
of the first.
