[llvm-dev] PSA: debuginfo-tests workflow changing slightly

I sorta enjoy debugging stuff like this, so if you don't mind, I'll dig
into it once I get a chance -- traveling so, my access is a bit sketchy
right now.

I'll see if I can grab the logs and let you know if I find anything
interesting.

[llvm-dev] PSA: debuginfo-tests workflow changing slightly

Definitely welcome to look into it, but unless you have physical access to
one of these buildbots, I don't think we should commit anything else
speculatively without having someone who does have physical access first
confirm it.

[llvm-dev] PSA: debuginfo-tests workflow changing slightly

Hi Zachary:

I was able to reproduce the greendragon results locally (OSX), and fix the
problem by excluding 'debuginfo-tests' from check-clang -- this prevents
them from being added twice, once for check-clang and again for
check-debuginfo.

Below are the minimized patches I used to reproduce and fix the problem --
based on your originals.

I've verified these patches work when including debuginfo-tests in either
clang/test or llvm/projects.
