I originally added this test there, but testing things there as-is is presents a disadvantage: The unittests don't link against liblldb but the individual lldb libraries, so the methods that figure out where the Clang Resource Dir (and pretty much any other directory for that matter) will report something like this:
`/path/to/llvm/build/tools/lldb/unittests/lib/clang/9.0.0`. So, the best this test could do is set that the filespec had a directory and not a filename set, which is what this test already does.
That being said, the way MacOS is being tested is much nicer. I could do a small refactor so the non-MacOS posix implementation is closer to the MacOS implementation and add a Linux test (and eventually a windows test) to `unittests/Expression/ClangParserTest.cpp` as well. What do you think?
