    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.
