[PATCH] D92736: [lld/mac] Use xxhash instead of MD5 for computing the UUID

> The point is if you produce a binary with ld64 with or without local symbols, with or without debug info (STABS debug map) -- at link time -- it will produce the same UUID.

I understand that part. I'm wondering what the use case is where this is important. In my experience, people build with debug info and then strip (which gives you binaries with and without debug info and with matching UUID even with the elf scheme), instead of building once with debug info and once without. So my question above is: Do you do two separate builds, one with debug info and one without, instead of using strip? If so, why?
