Log message:
	* basic-block.h (last_basic_block): Declare.
	(expunge_block_nocompact): Declaration removed.
	(compact_blocks): Declare.
	* cfg.c (last_basic_block): New variable.
	(expunge_block_nocompact): Removed.
	(expunge_block): Do not compact basic blocks.
	(compact_blocks): New.
	* cfganal.c (flow_call_edges_add): Use the fact that bb indices no
	longer change.
	* cfgbuild.c (find_basic_blocks_1, find_basic_blocks): Set
	last_basic_block.
	* cfgcleanup.c (merge_blocks_move_predecessor_nojumps): Do not change
	real positions of blocks.
	(delete_unreachable_blocks): Simplified -- quadratic behavior now
	cannot occur.
	(cleanup_cfg): Compact blocks.
	* cfgrtl.c (create_basic_block): Insert basic blocks to the end of
	basic_block_info varray.
	(flow_delete_block): Comment update.
	(back_edge_of_syntactic_loop_p): Modify position check code.
	(verify_flow_info): Update checking.
	* flow.c (calculate_global_regs_live): Use FOR_EACH_BB.
	* ifcvt.c (SET_ORIG_INDEX, ORIG_INDEX): Removed.
	(find_if_case_1, find_if_case_2, if_convert): Use the fact that bb
	indices no longer change.
	* lcm.c (optimize_mode_switching): Replace n_basic_blocks with
	last_basic_block.
	* predict.c (estimate_bb_frequencies): Remove unneccessary code.
	* profile.c (branch_prob): Compact blocks.
	* sched-rgn.c (find_rgns): Replace n_basic_blocks with
	last_basic_block.
