Fix profile count maintenance in vectorizer peeling.
This patch changes the code to save/restore profile counts for
the epliog loop (when not using scalar loop in the epilog)
instead of scaling them down and then back up, which may lead
to problems if we scale down to 0.
Tested on x86_64-pc-linux-gnu.
gcc/ChangeLog:
* tree-vect-loop-manip.cc (vect_do_peeling): Save/restore profile
counts for the epilog loop.
