Bug fixes:

  - The opt-in “file_macro sloppiness” mode has been removed so that the input
    file path now is always included in the direct mode hash. This fixes a bug
    that could result in false cache hits in an edge case when “file_macro
    sloppiness” is enabled and several identical source files include a
    relative header file with the same name but in different directories.

  - Statistics files are no longer lost when the filesystem of the cache is
    full.

  - Bail out on too hard Clang option “-MJarg” (in addition to the previous
    bailout of “-MJ arg”).

  - Properly handle color diagnostics in the depend mode as well.
