[MIPS] Map 'move' to 'or'.

The MIPS assembly idiom 'move' now maps to the 'or' machine instruction. This
change affects microMIPS, MIPS32, MIPS64.

2015-08-12  Simon Dardis  <simon.dardis@imgtec.com>

opcodes/

* micromips-opc.c (micromips_opcodes): Re-order table so that move
based on 'or' is first.
* mips-opc.c (mips_builtin_opcodes): Ditto.

bfd/

* elfxx-mips.c (STUB_MOVE): Change to use 'or' only.
(mips_o32_exec_plt0_entry, mips_n32_exec_plt0_entry,
mips_n64_exec_plt0_entry, micromips_insn32_o32_exec_plt0_entry):
Update to use 'or' instead of 'addu/daddu'.
(_bfd_mips_elf_finish_dynamic_symbol): Update usage of STUB_MOVE.
(move_insns_32): Reorder table.

gas/

* config/tc-mips.c (move_register): Change to use 'or' only.
