  1. opt: fix panic in generating tuple IN constraints 

    Fixes cockroachdb#27016.

Previously this code would panic if there were no constrainable columns.
I've added an equivalent test case to the one provided, but it will be
difficult to run the test provided until cockroachdb#27034 lands. I suspect the
problem there was with placeholders.

We should also consider adding prepared statement support to opt_tester
so that we can test situations like that in the future.

Release note (bug fix): Fix a panic in the optimizer with IN filters.
