beam_validator: Track types by value rather than by register
This is a rather subtle but important distinction. While tracking types on a per-register basis is fairly effective, it forces us to track which registers alias each other, and makes it tricky to infer types over large blocks of code as instruction arguments may have been clobbered between definition and inference. Tracking types on a per-value basis makes us immune to these problems.
