PR middle-end/42245
* sel-sched-ir.c (sel_recompute_toporder): New. Use it...
(maybe_tidy_empty_bb): ... here. Make static. Add new
argument. Update all callers.
(tidy_control_flow): ... and here. Recompute topological order
of basic blocks in region if necessary.
(sel_redirect_edge_and_branch): Change return type. Return true
if topological order might have been invalidated.
(purge_empty_blocks): Export and move from...
* sel-sched.c (purge_empty_blocks): ... here.
* sel-sched-ir.h (sel_redirect_edge_and_branch): Update prototype.
(maybe_tidy_empty_bb): Delete prototype.
