re PR target/54564 (Broken __builtin_ia32_vfmadds[sd]3) 

	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.
