AFAIK this test won't have a direct equivalent after this commit; but they are tested incidentally by a few ([intFromString](https://github.com/llvm/llvm-project/blob/72768d9bb8ad3e97a852270726f04d7167d9ef50/clang/test/Analysis/out-of-bounds-diagnostics.c#L262) and [intFromStringDivisible](https://github.com/llvm/llvm-project/blob/72768d9bb8ad3e97a852270726f04d7167d9ef50/clang/test/Analysis/out-of-bounds-diagnostics.c#L269)) in `out-of-bounds-diagnostics.c`. String literals are simple and straightforward regions, so I think this coverage is sufficient for them; but I could migrate this test case if you wish.
