[libc++][patch] Fix a lit.cfg bug: the CMake build compiler is ignored

[Michael Gottesman]

Hey Sebastian.

Your patch looks fine to me except that you should indent in the inferring section so it looks more like this:

 if cxx_under_test is None:
     cxx_under_test = getattr(config, 'cxx_under_test', None)
 
<-- Indent more in starting here
  +if cxx_under_test is None:
       # If no specific cxx_under_test was given, attempt to infer it as clang++.
       clangxx = lit.util.which('clang++', config.environment['PATH'])
       if clangxx is not None:
           cxx_under_test = clangxx
           lit.note("inferred cxx_under_test as: %r" % (cxx_under_test,))
<-- And stopping here.

Otherwise if cxx_under_test is initially not None, you are checking one more time that cxx_under_test is None than you need to.
