John Hawthorn 0bab6310d6 Find query_source_location using lazy Enumerator
This way, we only need to filter the backtrace up to the first non-noise
stack frame.

This also updates noise to be able to deal with being passed a lazy
enum. We don't need this anywhere, but it seemed better for this to be
consistent.
