Alex Behm 9a9886ee37 IMPALA-2950: Fully resolve exprs before wrapping with TupleIsNullPredicates. ...

The bug: In SingleNodePlanner.createInlineViewPlan() we need to wrap some
exprs with TupleIsNullPredicates to preserve correctness if the inline view
is outer joined. The bug was that we used to perform this wrapping on
the rhs of the inline view's smap, and not the final output smap after
those rhs exprs have been resolved against the physical output of the
inline view's plan root. As a result, the TupleIsNullWrapping did not
work correctly for deeply nested inline views with exprs that require
wrapping at various nesting levels.

The fix: Resolve the exprs against the physical output of the inline view's
plan root before performing the TupleIsNullPredicate wrapping.
