This is a fix for the issue reported at https://reviews.llvm.org/D110043#3019942: The ElementSize is a uint64_t and as such may be larger than the index space, or be negative in the index space. This is UB, but shouldn't cause assertion failures. We address this by detecting whether the size is too large and use a zero index in that case (which is always conservatively correct).
