re PR target/80298 (<x86intrin.h> incompatible with -mno-sse)

	PR target/80298
	* config/i386/mmintrin.h: Add -msse target option when __SSE__ is
	not defined for x86_64 target.  Add -mmmx target option when __SSE2__
	is not defined.
	* config/i386/mm3dnow.h: Add -msse target when __SSE__ is not defined
	for x86_64 target.  Handle -m3dnowa option.
