Move VF based dependence check
The following moves the check whether the maximum vectorization
factor determined by data dependence analysis is in conflict with
the chosen vectorization factor to after the point where we applied
both the SLP and the unrolling adjustment to the vectorization
factor. We check the latter before applying unrolling, but the
SLP adjustment can result in both missed optimization and wrong-code.
* tree-vect-loop.cc (vect_analyze_loop_2): Move check
of VF against max_vf until VF is final.
