Description

Factor out plan normalization functions to later use those in single-pass Analyzer testing.

In the single-pass Analyzer proposal we discussed one of the ways to test the single-pass Analyzer - to run tests in dual mode (both single-pass and fixed-point Analyzers) and compare the logical plans. To do that we need to perform plan normalization.
