[PATCH] D91895: [Clang] improve -Wimplicit-fallthrough GCC compat

[Nick Desaulniers via Phabricator via cfe-commits]

I'm happy to modify the patch based on feedback from LKML, though

  switch (x) {
    case 0:
      ++x;
    default:
      break;
  }

is the important case that's 99% of the differences between GCC and Clang, which should not get removed from this patch.
