The goal of this task is to write tests for the new optimizer involving $and/$or with hundreds or thousands of arguments.

The intention of these tests is to stress the ABT and to ensure that nothing stack overflows while the ABT is being generated, when the ABT is lowered to SBE, or when the SBE plan is executed.
