[TEST] Example file

See attached test case.

    void doSomething(char c)
    {
        switch (c) {
            case 'a':
                [[clang::fallthrough]];
    label:
            default:
                break;
        }
    }

The label "label" above is between the cases and causes the clang::fallthrough
not at end warning:

    label.cpp:9:13: warning: fallthrough annotation does not directly precede
switch label [-Wimplicit-fallthrough]
                [[clang::fallthrough]];
                ^
    1 warning generated.

It would be much nicer if the fall through was allowed before the label. After
the feels weird here.
