PR target/18331
	* config/mmix/mmix.md ("*movdicc_real_reversible"): Rename from
	"*movdicc_real".  Only match reversible comparisons.
	("*movdicc_real_nonreversible"): New pattern, split from
	"*movdicc_real".  Match only nonreversible comparisons.  Exclude
	reversed alternatives.
	("*movdfcc_real_reversible", "*movdfcc_real_nonreversible"):
	Similar.
