* haifa-sched.c (is_cfg_nonregular): Change return type to
an int. No longer compute "estimated" number of edges. Use
computed_jump_p instead of duplicating the code. Fixup/add
some comments.
(build_control_flow): Returns a value indicating an irregularity
in the cfg was detected. Count the number of edges in the cfg.
allocate various edge tables.
(find_rgns): No longer look for unreachable blocks.
(schedule_insns): Do not allocate memory for edge tables here.
Free memory for edge tables before returning. Do not perform
cross block scheduling if build_control_flow returns nonzero.
* flow.c (compute_preds_succs): More accurately determine when
a block drops in.
Fixes various compile hangs after haifa cleanup.
