Change subject: IMPALA-7895: Incorrect expected results for 
spillable-buffer-sizing.test
......................................................................


Patch Set 3:

Tim, thanks for the review and for pointing out the test failure.

Tracked down the bug. We have a whole pile of "to sql" code in the FE, called 
from the BE, without unit tests. This code works with an AST without analysis, 
which triggered the NPE we saw earlier. The new patch includes a starter test. 
I'll add others in a separate patch.

Please take a second look when you get a chance. Thanks!
