David Wendt 362294181f Implement constant pool default values (index 0).
All constant pools in an ABC file are actually numbered starting from one; there's an implicit 0 entry not stored in the file that the runtime is expected to retrieve when pulling constants from the pool.

The AVM2/ABC spec only mentions this in passing.

David Wendt 04879fc419 Implement class traits.
This allows the AVM to declare classes, which necessitated some refactoring to avoid double-borrows or having to do something "magic" that would dodge virtual properties.

David Wendt 88957b2b3d Add stub builtins for Object and Function. These are more-or-less identical to the way we did it in AVM1 (e.g. no fancy player globals file) 2020-07-13 17:43:24 -04:00

David Wendt 115f0393aa Add `call` method to the object trait. Only functions are callable in AVM2, all others error out. 2020-07-13 17:42:48 -04:00
David Wendt 7f60fab1e5 Add the bare minimum necessary to get opcodes out of an ABC and into an interpreter loop.
Surprisingly enough, the "bare minimum" includes a stack, object model, and values already.
