Title: New Regime for Address and VPointers

The major revisions of this pull request are:

1. Remove the third position from v*s and Return results
2. All objects and closures created in the interpreter directly have an address allocated for them, and a VPointer results
3. All places in the interpreter that need to work with objects and closures fetch from a VPointer
4. There is *never* a VPointer nested within another VPointer, which would warrant things like deep-lookup, etc.
5. Each object gets a *unique* VPointer for its entire lifetime. Mutations to the object are reflected by functionally updating the object at the address referred to by the VPointer.
