I have been working with @bd1976bris to try out these changes with FastBuild for our internal build infrastructure and I am happy to report that I have a PoC working based on this and I was recently able to get distribution to work.

While working with Tobias, I back-ported this PR to LLVM 19 and wired up the Clang and LLD side changes.
