The LLVM Nightly Test suite contains a number of executable tests, but these typically take much longer to run and so are run by the CI infrastructure on a variety of different platforms.

I incorrectly assumed "nightly" referred to some git branch, but I see
no mentioning of "nightly" looking at `git branch -a`, so it must be
located somewhere else?

Googling "LLVM Nightly Test" directs me to
http://llvm.org/docs/lnt/tests.html where it says "LLVM Makefile
test-suite (aka LLVM Nightly Test), Note: The Makefile test-suite is
deprecated.".

Where are these tests located? What git repo/branch to checkout and in
what directory can I find the tests?

My apologies for my stupidity. :)
