This patch adds a check in validation for delinearization to ensure that
the offset calculation does not overflow. If it overflows, different
array accesses (e.g., `A[0][0]` and `A[1][0]`) could map to the same
linear index, leading to incorrect behavior.
For fixed-size arrays, the check is relatively straightforward. However,
for dynamic-size arrays (i.e., arrays where the size is not known at
compile time), it's difficult to prove this statically, and it going to
fail for almost all cases. Maybe we need to add some runtime checks or
reasoning based on `inbounds` like LAA does.
Fixes the test cases added in #169048.
