PR tree-optimization/77536
* tree-ssa-loop-manip.c (niter_for_unrolled_loop): New function.
(tree_transform_and_unroll_loop): Use above function to compute the
estimated niter of unrolled loop and use it when scaling profile.
Also use count info rather than frequency if it's non-zero.
* tree-ssa-loop-manip.h niter_for_unrolled_loop(): New declaration.
* tree-vect-loop.c (scale_profile_for_vect_loop): New function.
(vect_transform_loop): Call above function.
gcc/testsuite
* gcc.dg/vect/pr79347.c: Revise testing string.
