* config/mips-opcode.h: Moved to opcode/mips.h.

	* config/mips-opcode.h: Moved to opcode/mips.h.
	* config/tc-mips.c: Include opcode/mips.h rather than
	mips-opcode.h.
	(append_insn): An extra NOP is only needed after instructions
	which set HI or LO, not after instructions which read it.
	(macro_build, mips_ip): Support new 'E', 'G' and 'B' arguments.
	(macro): cfc1 and ctc1 now take "t,G" rather than "t,d".
	* config/tc-mips.h (struct mips_opcode): Don't define.
	* config/mips-big.mt, config/mips-lit.mt (TARG_CPU_DEPENDENTS):
	Set to $(srcdir)/../include/opcode/mips.h.

	Get the MIPS assembler up to speed with other gas changes:

	* config/obj-ecoff.c (ecoff_set_vma, ecoff_frob_symbol):
	Removed; don't change the symbol value.
	(ecoff_build_symbols, ecoff_build_procs, ecoff_frob_file): Use
	bfd_asymbol_value rather than S_GET_VALUE to include section
	vma in symbol value.
	(ecoff_frob_file): Ignore BSF_SECTION_SYM symbols, since ECOFF
	doesn't output them.  Set the vma of sections.
	* config/obj-ecoff.h: Don't define obj_frob_symbol.
	* config/tc-mips.c (tc_gen_reloc): Adjustment by section vma is no
	longer necessary.
	(various): use valueT rather than long.
