[PATCH] Remove backedge handling support in tree-ssa-threadupdate.c
* tree-ssa-threadupdate.c (register_jump_thraed): Assert that a
non-FSM path has no edges marked with EDGE_DFS_BACK.
(ssa_redirect_edges): No longer call mark_loop_for_removal.
(thread_single_edge, def_split_header_continue_p): Remove.
(bb_ends_with_multiway_branch): Likewise.
(thread_through_loop_header): Remove cases of threading from
latch through the header. Simplify knowing we won't thread
the latch.
(thread_through_all_blocks): Simplify knowing that only the FSM
threader needs to handle backedges.
