    RISC-V: Reorganize mangle_builtin_type.[NFC]
    
    Hi, this patch fixed my mistake in the previous commit patch.
    Since "mangle_builtin_type" is a global function will be called in riscv.cc.
    It's reasonable move it down and put them together stay with other global functions.
    
    gcc/ChangeLog:
    
            * config/riscv/riscv-vector-builtins.cc (mangle_builtin_type): Move down the function.
