Fixes for profile count/probability maintenance
Verifier checks have recently been strengthened to check that
all counts and probabilities are initialized. The checks fired
during autoprofiledbootstrap build and this patch fixes it.
Tested on x86_64-pc-linux-gnu.
gcc/ChangeLog:
* auto-profile.cc (afdo_calculate_branch_prob): Fix count
comparisons
* tree-vect-loop-manip.cc (vect_do_peeling): Guard against zero
count
when scaling loop profile
