    opcodes/riscv-dis.c: Use bool type whenever possible
    
    Before changing the core disassembler, we take care of minor code clarity
    issues and improve readability.
    
    This commit replaces uses of int with bool whenever possible.
    
    opcodes/ChangeLog:
    
            * riscv-dis.c (no_aliases) Change type to bool.
            (set_default_riscv_dis_options): Use boolean.
            (parse_riscv_dis_option_without_args): Likewise.
            (riscv_disassemble_insn): Use boolean keywords.
