Else blocks with optional statements are not supported in CIL.
Currently, if the pp to CIL compiler comes across one of these in a pp
module, it just drops the block and outputs a warning. Fortunately,
these are very rare. In fact, this is the only place in refpolicy where
an optional else block is used, and it is not clear if it is even
needed. This patch is untested, and is more to spark discussions to see
if there are any thoughts about whether or not this piece of policy is
needed.

In practice, it's probably not used, so I think we could remove it.

Hi Christopher,
I do not see this patch in the repo yet. Was it missed perhaps?
Thanks,
Jason
