* config/tc-hppa.h (tc_frob_label): Define.

	* config/tc-mips.c: Many changes to support simple assembler
	optimization.
	(insn_label, prev_insn, prev_prev_insn, dummy_opcode,
	prev_insn_valid, prev_insn_frag, prev_insn_where,
	prev_insn_fixp, prev_insn_is_delay_slot): New static
	variables.
	(insn_uses_reg, mips_no_prev_insn, mips_emit_delays,
	mips_align, s_stringer, s_mips_space): New static functions.
	(mips_define_label): New global function.
	(md_pseudo_table): For "ascii", "asciz", "asciiz", call
	s_stringer.  Changed argument to float_cons from 0 or 1 to 'f'
	or 'd'.  For "space" call s_mips_space.
	(md_begin): Call mips_no_prev_insn.
	(append_insn): Only insert necessary NOP instructions.
	(macro): Call mips_emit_delays before setting mips_noreorder.
	Increment and decrement mips_noreorder rather than using
	save_reorder_condition.  Don't bother to use noreorder in
	M_L_DOB and M_L_DAB, since append_insn will not insert a NOP.
	(md_atof): Handle floating point numbers correctly for both
	big and little endian targets.
	(s_align, s_cons): Call mips_align rather than frag_align.
	(s_change_seg, s_cons): Call mips_emit_delays.
	(s_float_cons): Let float_cons do the work.
	(s_mipsset): Call mips_emit_delays when setting noreorder.
	* config/tc-mips.h (tc_frob_label): Define to be
	mips_define_label.
