Zalathar ab154e6999 coverage: Store bcb_needs_counter in a field as a bitset
This makes it possible for other parts of counter-assignment to check whether a
node is guaranteed to end up with some kind of counter.

Switching from `impl Fn` to a concrete `&BitSet` just avoids the hassle of
trying to store a closure in a struct field, and currently there's no
foreseeable need for this information to not be a bitset.
