Edward Paget 4e66158fb7 topdown: cache undefined rule evaluations (#5523 )

With this change, `undefined` outcomes of complete rule evaluations
are now also cached. Previously, only defined results had been cached,
and empty partial sets/objects.

In the case of partial rules with string keys, the introduction of ref heads
changed how they had been evaluated: Before, they had been evaluated
as partial sets, and thus got cached when empty. After, they had been
evaluated as complete rules (with ref heads), and if they were undefined,
they had _not_ been cached. This caused a performance regression.

Fixes #593.
