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.
