Subject: CRIS: Don't apply PATTERN to insn before validation (PR 110144)

CRIS: Don't apply PATTERN to insn before validation (PR 110144)

Oops.  The validation was there, but PATTERN was applied
before that.  Noticeable only with rtl-checking (for example
as in the report: "--enable-checking=yes,rtl") as this
statement was only a (one of many) straggling olde-C
declare-and-initialize-at-beginning-of-block thing.

	PR target/110144
	* config/cris/cris.cc (cris_postdbr_cmpelim): Don't apply PATTERN
	to insn before validating it.
