Log:
    PR target/64338
    * config/i386/i386.c (ix86_expand_int_movcc): Don't reverse
    compare_code when it is unconditionally overwritten afterwards.
    Use ix86_reverse_condition instead of reverse_condition.  Don't
    change code if *reverse_condition* returned UNKNOWN and don't
    swap ct/cf and negate diff in that case.

    * g++.dg/opt/pr64338.C: New test.
