* basic-block.h (rediscover_loops_after_threading): Declare.
* tree-ssa-dom.c: Include cfgloop.h.
(tree_ssa_dominator_optimize): Discover loops and some basic
properties. Remove forwarder blocks recreated by loop header
canonicalization. Also mark backedges in the CFG.
* tree-ssa-threadupdate.c: Include cfgloop.h
(rediscover_loops_after_threading): Define.
(struct local_info): New field, JUMP_THREADED.
(prune_undesirable_thread_requests): New function.
(redirect_edges): Clear EDGE_ABNORMAL. If edges were threaded
then record that fact for the callers of redirct_edges.
(thread_block): If BB has incoming backedges, then call
prune_undesirable_thraed_requests. Note when we are
going to have to rediscover loop information. Return a
boolean indicating if any jumps were threaded.
(thread_through_all_blocks): Bubble up boolean indicating
if any jumps were threaded.
* Makefile.in (tree-ssa-dom.o): Depend on cfgloop.h
(tree-ssa-threadupdate.o): Similarly.
