Commit Message

Reuse `SublistResult` for `LoadNextMsgMulti` (#5316)

This PR adds `(*Sublist).MatchInline(..., *SublistResult)` so that we
can reuse the same `SublistResult` multiple times when we know that
we're going to be matching multiple times in rapid succession. It's not
full pooling but helps out nicely.

On the `JetStreamConsumeWithFilters/.*` benchmark, this reduces the
number of `SublistResult` allocations in `LoadNextMsgMulti()` from 10GB
down to 4GB:
