Use member in ClobberWalker, and add wrapper APIs that don't require BatchAAResults (and just create it internally). Something I previously missed was updating the unit tests, and creating the BatchAA instances there does get pretty annoying for no benefit.

This patch now only ensures that individual queries use BatchAA, but doesn't yet share BatchAA across multiple queries anywhere. I'll land that part separately.
