	* mips-opc.c (mips_builtin_opcodes): Move M_LD_OB and M_SD_OB
	macros before their corresponding MIPS III hardware instructions.

	gas/
	* config/tc-mips.c (macro)[M_LD_OB, M_SD_OB]: Handle 64-bit ABIs.

	gas/testsuite/
	* gas/mips/lineno.s: Convert to o32.
	* gas/mips/lineno.d: Adjust patterns accordingly.  Force the o32
	ABI.
