Andrew Waterman 63a25ea0de RISC-V: Fix disassembly of c.addi4spn, c.addi16sp, c.lui when imm=0 
These are all invalid instructions, so they should not disassemble.

opcodes/ChangeLog

2017-10-24  Andrew Waterman  <andrew@sifive.com>

        * riscv-opc.c (match_c_addi16sp) : New function.
        (match_c_addi4spn): New function.
        (match_c_lui): Don't allow 0-immediate encodings.
        (riscv_opcodes) <addi>: Use the above functions.
        <add>: Likewise.
        <c.addi4spn>: Likewise.
        <c.addi16sp>: Likewise.
