1848b37300 [stdlib] Add bitset constructs
Bitsets implement sorted sets over nonnegative integers up to a predetermined maximum value.

These are intended to replace _UnsafeBitMap. The latter will be removed once its usages are eliminated.

- _UnsafeBitset.Word is the underlying abstraction, implementing a bitset using a single UInt value.
- _UnsafeBitset is a view over a contiguous range of words.
- _Bitset is a COW value type implementing the same construct.
