Review comment:
@kgyrtkirk The original issue for which HIVE-22578 was opened is being fixed
by HIVE-22824 (this pull request's change). CBO path was failing because
JoinProjectTranspose rule was removing project containing windowing (creating
wrong AST).
Fall to non-cbo path should happen only for queries for which CBO isn't
supported (and that will happed before fixUpAfterCbo). So I believe it is okay
to change AST at this point.
