Sure of course.  As far as I remember, that portion is originally based
on INSN_CLASS_D_AND_ZFA case and later influenced by INSN_CLASS_F_AND_C.
 I need to write a tidying commit for other cases but for this
extension, I prefer your first proposal directly (similar to
INSN_CLASS_F_AND_C).

I'll submit v4 (change is only here) in a few minutes!

Thanks,
