      Description

      Two tests (LongReverse and the base64 tests in StringFunctions) run their tests over all lengths from 0..some length. Both take several minutes to complete. This adds a lot of runtime for not much more confidence. If instead we pick a set of 'interesting' (including powers-of-two, prime numbers, edge-cases) lengths, we can get a similar amount of confidence while significantly reducing the runtime of expr-test.
