    LoongArch: Remove unused and incorrect "sge<u>_<X:mode><GPR:mode>" define_insn
    
    If this insn is really used, we'll have something like
    
        slti $r4,$r0,$r5
    
    in the code.  The assembler will reject it because slti wants 2
    register operands and 1 immediate operand.  But we've not got any bug
    report for this, indicating this define_insn is unused at all.
    
    Note that do_store_flag (in expr.cc) is already converting x >= 1 to
    x > 0 unconditionally, so this define_insn is indeed unused and we can
    just remove it.
    
    gcc/ChangeLog:
    
            * config/loongarch/loongarch.md (any_ge): Remove.
            (sge<u>_<X:mode><GPR:mode>): Remove.
