Steven Hawkins resolved TEIID-5029.
-----------------------------------
Resolution: Done
Updated the logic to account for when both children are access nodes - which will only
occur in limited circumstances when pushdown is initially inhibited (such as with a nested
cross join).
There is a follow on enhancement to allow for additional pushdown planning after this
particular scenario, but that's a very low priority.
