Remove several internal property types for primitive objects. (#1399)

Browse Source 
Class and value internal properties are always exists for primitive
types (e.g. Boolean, Regex) so they can be stored right after the
object. This improve property access (since internal properties are
searched by a slow linear algorithm) and reduces memory consumption,
since only 8 byte is allocated for these two properties instead of
16 which is the size of a property pair.
