[PATCH 38/46] i386: Allow MMXMODE moves without MMX

In 64-bit mode, allow MMXMODE moves with SSE when MMX is disabled.

	PR target/89021
	* config/i386/mmx.md (MMXMODE:mov<mode>): Check TARGET_MMX_INSNS
	instead of TARGET_MMX.
	(MMXMODE:*mov<mode>_internal): Likewise.
	(MMXMODE:movmisalign<mode>): Likewise.
