[PATCH] Added testing to test migration of files in a compilation database

[Edwin Vane]

  Have you tried this test on Windows?

  These tests should be added:
  # `-p` is specified with no files and no `-include`.
  # `-p` is specified with *both* files and `-include`.
  # Until you fix the compilation database auto-detect bug, You should have another XFAIL test for when `-p` is not specified, >=1 source file is provided, and no `--`.

You can avoid this hack by putting compilations.cpp and compilatiosn_expected.cpp in a subdirectory called "Inputs". I believe files here are automatically skipped by LIT when looking for tests. While you're at it, put the .json file in there too.
