    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.
