Description

Motivation and Context
Allow the Presto Verifier users to substitute functions, ex., nondeterministic functions, to make the test query comparable with TEST and CONTROL.
Impact
The feature is enabled only when the parameter --function-substitutes is set.
Test Plan
Unit tests in TestQueryRewriter.
