gas/
	* config/tc-mips.c (enum small_ex_type): Remove.
	(imm_unmatched_hi): Remove.
	(md_assemble): Remove use of imm_unmatched_hi.  Remove the last
	argument from calls to append_insn.
	(append_insn): Remove unmatched_hi parameter; check reloc_type[0]
	instead.
	(macro_build): Update append_insn calls.
	(mips16_macro_build, macro_build_lui): Likewise.
	(mips_ip): Rework handling of small expressions.  Move explicit
	relocation handling into my_getSmallExpression.  Assume that the
	value of 'o' operands is zero if there is only one bracketed
	expression left.
	(percent_op): Make constant.  Record the BFD relocation code
	associated with each operator.
	(my_getSmallParser, my_getPercentOp): Remove.
	(parse_relocation): New function.
	(my_getSamllExpression): Rework.  Fill in relocations here
	rather than in mips_ip.

gas/testsuite
	* gas/mips/elf-rel8.[sd], gas/mips/elf-rel9.[sd],
	gas/mips/elf-rel10.[sd], gas/mips/elf-rel11.[sd]: New tests.
	* gas/mips/mips.exp: Run elf-rel8 and elf-rel9 for all elf
	targets.  Run elf-rel10 and elf-rel11 for NewABI targets.
