Fix profile update after prologue peeling in vectorizer

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.

gcc/ChangeLog:

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