This patch fixes pr34283, which exposed that the computation of maximum legal width for vectorization was wrong, because it relied on MaxInterleaveFactor to obtain the maximum stride used in the loop, however not all strided accesses in the loop have an interleave-group associated with them. Instead of recording the maximum stride in the loop, which can be over conservative (e.g. if the access with the maximum stride is not involved in the dependence limitation), this patch tracks the actual maximum legal width imposed by accesses that are involved in dependencies.
