tree-wide: adjust fall through comments so that gcc is happy
gcc 7 adds -Wimplicit-fallthrough=3 to -Wextra. There are a few ways we could deal with that. After we take into account the need to stay compatible with older versions of the compiler (and other compilers), I don't think adding __attribute__((fallthrough)), even as a macro, is worth the trouble. It sticks out too much, a comment is just as good. But gcc has some very specific requiremnts how the comment should look. Adjust it the specific form that it likes. I don't think the extra stuff we had in those comments was adding much value. (Note: the documentation seems to be wrong, and seems to describe a different pattern from the one that is actually used. I guess either the docs or the code will have to change before gcc 7 is finalized.)
