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.

The new set does not allocate memory when the size of the array is reduced.
Furthermore the [[PutObject]] method directly calls the new length setter.

This patch changes define own property to search a property only once.
Currently all existing properties are searched at least twice, sometimes
three times which is not optimal.
