basic-block.h (has_abnormal_outgoing_edge_p): Moved here from...
* basic-block.h (has_abnormal_outgoing_edge_p): Moved here from...
* tree-inline.c (has_abnormal_outgoing_edge_p): Remove.
* gimple-ssa-isolate-paths.c: Include tree-cfg.h.
(find_implicit_erroneous_behaviour): If a block has abnormal outgoing
edges, then ignore it. If the statement exhibiting erroneous
behaviour ends basic blocks, with the exception of GIMPLE_RETURNs,
then we can not optimize.
(find_explicit_erroneous_behaviour): Likewise.
