    Use ix86_fp_comparison_operator in cbranchbf4 to avoid ICE.

    *jcc only supports ix86_fp_comparison_operator for CCFP, when
    comparison code is LT, there's an ICE. W/o AVX10.2, it's ok since
    do_compare_rtx_and_jump will transform LT to GT, but w/ AVX10.2 it
    goes directly into ix86_expand_branch which doesn't handle it.

    Use ix86_fp_comparison_operator in cbranchbf4.

    gcc/ChangeLog:

            * config/i386/i386.md (cbranchbf4): Use
            ix86_fp_comparison_operator instead of comparison_operator.

            * gcc.target/i386/pr117452.c: New test.
