Fix nb_iterations_estimate calculation in tree-vect-loop.c

vect_transform_loop has to reduce three iteration counts by the vectorisation factor: nb_iterations_upper_bound, nb_iterations_likely_upper_bound and nb_iterations_estimate. All three are latch execution counts rather than loop body execution counts. The calculations were taking that into account
