The abstraction for validating the IR is brittle, as it depends on details of how QueryAssertions constructs the underlying query. We remove it from the QueryAssertions API for now. Additionally, clean up the tests in TestJsonStringArrayExtractScalar, which were unnecessarily complex.
Non-determinism depends on the body of the lambda expressions passed to the function. That's handled elsewhere.
@hashhar, I made a few additional changes. Mind taking a look again? |

I don't know/cant verify impact of " Mark array and map processing functions as deterministic " since I couldn't find the code which determines a lambda as deterministic or not.
LGTM otherwise.
