Replace gnu-ism: __attribute__ ((fallthrough));

__attribute__ ((fallthrough)); is only in GCC after version 7.  Not
supported by other cc, and in fact throws warnings on other cc.

The comment "/* FALLTHOUGH */" has the same effect when
-Wimplicit-fallthrough=X is used, with X being 1, 2, 3, or 4.
