This is a failure to handle return-slot-optimization in IPA-PTA properly. For
D.2098 = foo (); [return slot optimization]
we have to make foos return function part point to D.2098. That requires
some re-org, making the function result varinfo always a pointer,
making sure to use *result for result-decl uses (if not DECL_BY_REFERENCE).
I have a patch, but as this bug only affects IPA-PTA I'm defering it to 4.7
as the patch also touches non-IPA parts.
