[PATCH] disas/sh4: Add missing fallthrough annotations

[Thomas Huth]

Add fallthrough annotations to be able to compile the code without
warnings with -Wimplicit-fallthrough. Looking at the code, it seems
like the fallthrough is indeed intended here, so the comments should
be appropriate.

 Note: The new lines use TABs since all the surounding code uses TABs, too.
