[PATCH] llvm-lit: Allow compiler-rt tests to run from the source tree

[Alexey Samsonov]

Thanks, this is certainly a nice-to-have feature!

I'm a bit sad that we might need to copy the magic you use in
test/profile/lit.cfg to numerous test/xsan/lit.cfg configs, and would
prefer some generic approach instead.
However, if you can't think of the good way to do it right now, feel free
to commit your change, we can revisit this later.
