This avoids returning false positives where only the indices are shared. As the indices are not mutated by array assignments (and are explicitly warned against mutation in general), we can ignore the case where _only_ the indices are aliasing.

Restricting this method for matching parent types is not generally informative -- the analysis is the same even if the types differ and in this manner we can get the more fine-grained analyses for all Dense and Strided arrays.
