Simon Dardis 40fc1451c6 [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.
	(s_cpload, s_cpsetup, s_cprestore, s_cpreturn): Update to
	use or for move.
