RISC-V: Resurrect GP-relative disassembly hints
We missed a "_gp" when changing the GP symbol. To make sure that doesn't happen again, we now use the same definition everywhere (thanks, Nick). include/ChangeLog: 2017-04-03 Palmer Dabbelt <palmer@dabbelt.com> * elf/riscv.h (RISCV_GP_SYMBOL): New define. bfd/ChangeLog: 2017-04-03 Palmer Dabbelt <palmer@dabbelt.com> * elfnn-riscv.c (GP_NAME): Delete. (riscv_global_pointer_value): Change GP_NAME to RISCV_GP_SYMBOL. (_bfd_riscv_relax_lui): Likewise. opcodes/ChangeLog: 2017-04-03 Palmer Dabbelt <palmer@dabbelt.com> * riscv-dis.c (riscv_disassemble_insn): Change "_gp" to RISCV_GP_SYMBOL.
