[PULL 7/9] disas/sh4: Add missing fallthrough annotations

[Thomas Huth <thuth@redhat.com>]

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.
