[llvm] [ObjectSizeOffsetVisitor] Add a max recursion depth (PR #67479)

There is also recursion (though less likely) when visiting loads. I think it would be more robust (and a bit simpler) to instead do this depth inc/dec around the visit() call in https://github.com/llvm/llvm-project/blob/c55e5d4b18a34e9698314426d6e5077ee7e15025/llvm/lib/Analysis/MemoryBuiltins.cpp#L739, so that it covers everything.
