re PR target/64338 (ICE in swap_condition, at jump.c:628)

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.
