i386: Fix _mm_[u]comixx_{ss,sd} codegen and add PF result. [PR106113]

gcc/ChangeLog:

	PR target/106113
	* config/i386/i386-builtin.def (BDESC): Fix [u]comi{ss,sd}
	comparison due to intrinsics changed over time.
	* config/i386/i386-expand.cc (ix86_ssecom_setcc):
	Add unordered check and mode for sse comi codegen.
	(ix86_expand_sse_comi): Add unordered check and check a different
	CCmode.
	(ix86_expand_sse_comi_round):Extract unordered check and mode part
	in ix86_ssecom_setcc.
