[cfe-dev] Dependencies between tools

[Chris Gray via cfe-dev]

Hi Ilya, I actually didn't have much of a plan -- I just wanted to see if I
could do it.  I was assuming that there would be a mechanism for starting
asynchronous work that could add to the list of diagnostics, but I hadn't
gotten there yet.  I do think that coming up with some sort of way to have
inter-tool dependencies would be nice regardless of whether it's currently
feasible to add clang-tidy diagnostics to clangd.  (I guess I'm saying that
both problems will eventually need to be solved, and it makes sense to
concentrate on them separately.)
