But it's not actually cloning the loop to the header edge but doing
more - adding a condition and re-wiring edges so the cloned loop
is no longer on the header edge.
So no, I don't think this is good to go.
Name loop_copy is used in gcc/cfg.c already.
gcc/ChangeLog:
* cfgloopmanip.c (force_single_succ_latches): Rename
loop_version to clone_loop_to_header_edge.
(lv_adjust_loop_entry_edge): Likewise.
(loop_version): Likewise.
(clone_loop_to_header_edge):
