(schedule_block): Free space associated with reg_pending_sets and
old_live_regs.
(schedule_insns): Free bb_{dead,live}_regs on first pass.
(sched_analyze_insn): Use EXECUTE_IF_SET_IN_REG_SET and then clear.
From-SVN: r14426
(init_regset_vector): Make global; don't take basic block times # of pseduos
as argument.
(life_analysis): Change all init_regset_vector calls.
Use free_regset_vector to release arrays only flow uses at end.
(allocate_for_life_analysis): Change init_regset_vector call.
Don't set regset_{size,bytes}.
(free_regset_vector): Call FREE_REG_SET to release any memory allocated
by each vector.
(propagate_block): Call FREE_REG_SET on dead/live.

* mips.c (epilogue_reg_mentioned_p): Delete unused function.
(mips_epilogue_delay_slots): Likewise.
(function_epilogue): Greatly simplify.
(mips_expand_epilogue): If we have a null prologue/epilogue,
then use a normal return insn. Emit blockage insns before
stack pointer adjustments.
(mips_can_use_return_insn): Renamed from simple_epilogue_p. All
callers changed. Do not use return insns if $31 is live in the
function or if generating profiling information.
* mips.h (DELAY_SLOTS_FOR_EPILOGUE): Delete.
(ELIGIBLE_FOR_EPILOGUE_DELAY): Likewise.
* mips.md (return): Remove expander and change the pattern to
look like a standard "return" insn.
(return_internal): Show use of $31 explictly.
(epilogue expander): Enable.

(\titlefonts): New macro to set title font styles, so italic etc. work
in @title.
(\titlefont): No longer needed.
(\titlepage): Call \titlefonts instead of \titlefont.
(\chapsf, \ssecsy, \ssecttsl): Correct magstep values.

(\kbdfont, \kbdexamplefont): New macros, parms that
tell @kbd what to do.
(\setkbdinputdistinct, \setkbdinputexample): New commands set them.
(\kbd): Use those parms.
From-SVN: r14387
(\onepageout): Leave only one line space above the footline, to be more
like plain. Suggested by Stephen Gildea.
(\evenfootline): Left one too many line spaces here, so reduce by two.
(\ifnottex): Another ignore command.
(\ifnothtml,\ifnotinfo): New commands.
(\doignore): Ignore brace characters, so mismatched braces in ignored
text do not cause complaints.
