Refactored EXTERNAL_REFERENCE handling.

Previously, the result of target_reference_address() could only be
read, writing to it would have had an architecture-dependent effect,
e.g. writing into the code on ia32, a no-op on arm, etc.

This refactoring-only CL turns this into a simple getter, making it
impossible to use incorrectly.

More to come...

Introduce raw accessors for type_feedback_info.

This pure refactoring is needed for another upcoming CL.

Make snapshots reproducible.

To keep the structure of the serializer more or less untouched, we use
some ingenious Corry-approved(TM) 3-step technology (a.k.a. "hack"):

   * Create copies of code objects.
   * Wipe out all absolute addresses in these copies.
   * Write out the cleaned copies instead of the originals.

In conjunction with --random-seed, our snapshots are reproducible now.

-GetHash (now GetHash & handlified GetOrCreateHash)
-GetIdentityHash (now GetIdentityHash & handlified GetOrCreateIdentityHash)
