Just curious, what changed the behavior?

Oh that was because I forgot to check remapping in consume(if:). Fixed now.
Creating arrays for `consume(ifAny:)` and friends incurs memory allocations and reference counting costs. Stamp out copies of `consume(if:)` for up to three different kinds and start using `RawTokenKindSubset` if more kinds need to be checked. This improves performance of parsing MovieSwiftUI by 5%. rdar://103774645
