What is the status of this patch? It has not been committed as far as I can tell.

I was looking into this coming from Rust, where we do worry a bit about LLVM calling `memcpy`, `memmove` or `memset` in ways that are not allowed by the C standard. This here would at least give us something to point to, though it doesn't answer the question "which C standard libraries have officially committed to guaranteeing these properties". Since this affects all compilers using LLVM, not just Clang, should this be put somewhere in the LLVM docs?
