tree-cfgcleanup.c (cfgcleanup_altered_bbs): New global variable.
* tree-cfgcleanup.c (cfgcleanup_altered_bbs): New global variable.
(remove_fallthru_edge): Use remove_edge_and_dominated_blocks.
(cleanup_control_expr_graph): Do not invalidate dominance info.
Record altered blocks.
(cleanup_control_flow, cleanup_forwarder_blocks): Removed.
(cleanup_control_flow_bb, split_bbs_on_noreturn_calls,
cleanup_tree_cfg_bb): New functions.
(remove_forwarder_block): Do not maintain the worklist of blocks.
Record altered blocks.
(cleanup_tree_cfg_1): Iterate over cfgcleanup_altered_bbs,
not over whole cfg.
(cleanup_tree_cfg): Do not iterate cleanup_tree_cfg_1. Only call
delete_unreachable_blocks if dominators are not available.
* tree-inline.c (optimize_inline_calls): Free dominance information
earlier.
* tree-flow.h (remove_edge_and_dominated_blocks,
cfgcleanup_altered_bbs): Altered.
* tree-cfg.c (replace_uses_by, tree_merge_blocks): Record altered
blocks.
(get_all_dominated_blocks, remove_edge_and_dominated_blocks): New
functions.
(tree_purge_dead_eh_edges): Use remove_edge_and_dominated_blocks,
do not invalidate dominators.
