    RISC-V: Fix vop_m overloaded C++ API name.
    
    According to https://github.com/riscv-non-isa/rvv-intrinsic-doc/tree/master/
    For "vop_m" intrinsics, C++ overloaded API does not have "_m" suffix.
    
    gcc/ChangeLog:
    
            * config/riscv/riscv-vector-builtins-shapes.cc (struct loadstore_def):
            Remove _m suffix for "vop_m" C++ overloaded API name.
