Key Paths
class PartialA partially type-erased key path, from a concrete root type to any resulting value type.
class AnyA type-erased key path, from any root type to any resulting value type. NOTE: older runtimes had Swift.AnyKeyPath as the ObjC name. The two must coexist, so it was renamed. The old name must not be used in the new runtime. _TtCs11_AnyKeyPath is the mangled name for Swift._AnyKeyPath.
