  Log Message:
  -----------
  [clang][test] Disallow using the default module cache path in lit tests

Make the default module cache path invalid when running lit tests so
that tests are forced to provide a cache path. This avoids accidentally
escaping to the system default location, and would have caught the
failure recently found in ClangScanDeps/multiple-commands.c.
