Fix profile upate after vectorizer peeling

[Jan Hubicka via Gcc-patches]

Hi,
This patch fixes update after constant peeling in profilogue.  We now reached 0 
profile
update bugs on tramp3d vectorizaiton and also on quite few testcases, so I am 
enabling the
testuiste checks so we do not regress again.

Bootstrapped/regtested x86_64, comitted.

gcc/ChangeLog:

        * tree-vect-loop-manip.cc (vect_do_peeling): Fix profile update after
