use query boilerplate for prove-predicate -- slightly inefficient
...
This requires us to allocate a single entry vector we didn't use to
allocate. I doubt this makes a difference in practice, as this only
occurs for cache misses.

As the comment explains, this is needed to prevent subtype from going
awry in higher-ranked cases, due to #33684 . The proper fix here is
introducing universes (#48536 ).
