* function.c (bb_active_p): Delete.
(dup_block_and_redirect, active_insn_between): New functions.
(convert_jumps_to_returns, emit_return_for_exit): New functions,
split out from..
(thread_prologue_and_epilogue_insns): ..here. Delete
shadowing variables. Don't do prologue register clobber tests
when shrink wrapping already failed. Delete all last_bb_active
code. Instead compute tail block candidates for duplicating
exit path. Remove these from antic set. Duplicate tails when
reached from both blocks needing a prologue/epilogue and
blocks not needing such.
* ifcvt.c (dead_or_predicable): Test both flag_shrink_wrap and
HAVE_simple_return.
* bb-reorder.c (get_uncond_jump_length): Make global.
* bb-reorder.h (get_uncond_jump_length): Declare.
* cfgrtl.c (rtl_create_basic_block): Comment typo fix.
(rtl_split_edge): Likewise. Warning fix.
(rtl_duplicate_bb): New function.
(rtl_cfg_hooks): Enable can_duplicate_block_p and duplicate_block.
* Makefile.in (function.o): Update dependencies.
