re PR rtl-optimization/63952 (bootstrap failure (ICE in prepare_cmp_insn) on s390x in libjava)
PR rtl-optimization/63952
* optabs.c (prepare_cmp_insn): Do not call can_compare_p for CCmode.
* config/s390/s390.md ("cbranchcc4"): Accept any s390_comparison.
Remove incorrect TARGET_HARD_FLOAT check and no-op expander code.
