Change subject: generic_iterators: short-circuit MergeIterState::PullNextBlock

generic_iterators: short-circuit MergeIterState::PullNextBlock
This is a micro-optimization to avoid testing every bit in the selection
vector when we've already counted up the number of set bits.
There was a lack of selection vector coverage in the existing fuzzy merge
tests, so I've modified them to randomly use one, and added a new test too.
