* cfgrtl.c (delete_insn_and_edges, delete_insn_chain_and_edges): New.
* rtl.h (delete_insn_and_edges, delete_insn_chain_and_edges): Declare
* basic-block.h (update_life_info, update_life_info_in_dirty_blocks,
delete_noop_moves): Return indeger.
* flow.c (ndead): New variable.
(propagate_block_delete_insn): Use delete_insn_and_edges; remove
BB argument; update callers.
(propagate_block_delete_libcall): Use delete_insn_chain_and_edges.
(life_analysis): Do not call purge_all_dead_edges.
(update_life_info): Return number of deleted insns; print statistics.
(update_life_info_in_dirty_blocks): likewise.
(delete_noop_moves): Use delete_insn_and_edges; print statistics;
return number of insns deleted.
* cse.c: Include timevar.h
(delete_trivially_dead_insns): Kill preserve_basic_blocks argument;
iterate until stabilizes; print statistics; return number of killed
insns.
* Makefile.in: (cse.o): Add timevar.h dependency
* rtl.h (delete_trivially_dead_insns): New.
* timever.def: Add TV_DELETE_TRIVIALLY_DEAD timer.
* toplev.c (rest_of_compilation): Update callers.
* cfgcleanup.c (try_optimize_cfg): Kill blocks.
(try_optimize_cfg): Do not update liveness.
(cleanup-cfg): Loop until try_optimize_cfg and dead code
removal stabilizes; use delete_trivially_dead_insns.
* cfgrtl.c (verify_flow_info): Sanity check outgoing edges.
