* tree-ssa-threadedge.c (simplify_conrol_stmt_condition): If we are
unable to find X NE 0 in the tables, return X as the simplified
condition.
(fsm_find_control_statement_thread_paths): If nodes in NEXT_PATH are
in VISISTED_BBS, then return failure. Else add nodes from NEXT_PATH
to VISISTED_BBS. */
* tree-ssa-threadupdate.c (duplicate_thread_path): Fix up edge flags
after removing the control flow statement and unnecessary edges.
