The enum_bitfields system never worked quite right, and always had edge cases where name resolution for the SFINAE would fail. Move everything over to use util::bitset, which can be constexpr and boils down to inline integer bitops in release mode. Improved util::bitset itself, moving the array-backed base implementation into a new util::sized_bitset, and making the single-inttype backed implementation the base case. Also added a distinction between | or |= (which work with real bit values) and + or += (which work with bit indexes).
