Please take a look.

This is just a quick replacement of raw pointer lists by handle lists.

Full handlification of the polymorphic code cache is complicated because
PolymorphicCodeCacheHashTableKey has to implement raw pointer interface of
HashTableKey. So there is no clean way to separate handlified code from raw
pointer code.
