* config/tc-mips.h (mips_flush_pending_output): Delete.
(mips_emit_delays): Declare.
(md_flush_pending_output): Use mips_emit_delays.
* config/tc-mips.c (mips_no_prev_insn): Remove parameter; always forget
the previous instructions.
(md_begin, append_insn, md_parse_option): Update callers.
(mips_emit_delay): Remove parameter. Move INSNS != 0 code to
start_noreorder.
(mips_align, s_change_sec, s_cons, s_float_cons, s_gpword)
(s_gpdword): Update callers.
(start_noreorder, end_noreorder): New functions.
(macro, macro2, mips16_macro, s_mipsset): Use them instead of
manipulating mips_opts or prev_nop_frag directly.
(mips_flush_pending_output): Delete.
