I just sent a review to llvm-commits that fixes it [1], called
"[PATCH] llvm-lit: Allow compiler-rt tests to run from the
source tree".  Sorry I didn't use Phabricator, but after
struggling for a while I couldn't figure out how to send both
the llvm and compiler-rt sides, and it's nonsense to review
either patch in isolation.

The sanitizer tests should be able to use the same mechanism
without patching llvm.
