We do have the option of not trying to determine anything about _1 in
situations like this..
I tried removing the op1_range() routine for addr_expr, and we pass all tests
just fine.

we would pick up non-null, if relevant,  during normal processing. It may not
be necessary to try to determine things like this during the outgoing edge
calculation.. especially if its causing issues...
