* config/tc-mips.c (mips16_ip): Handle %gprel modifier.

	(md_apply_fix): Handle BFD_RELOC_MIPS16_GPREL.

	* config/tc-mips.c (append_insn): Output jump instruction as a
	pair of 2 byte instructions, rather than as a single 4 byte
	instruction.

start-sanitize-r5900
	* config/tc-mips.c (md_begin): Correct test of mips_5900.
	(mips_ip): Don't check INSN_ISA for a macro.

end-sanitize-r5900
