Description
Right now, regalloc2 uses an entity-component-system sort of pattern with toplevel `Vec`s of `LiveBundle`, `VRegData`, and the like, and newtype'd index wrappers like `LiveBundleIndex`, `VRegIndex`, etc. We have a whole bunch of instances of `self.bundles[bundle.index()]...`.
Ideally we would make `bundles` a `Vec`-wrapper type that has an `Index` implementation that natively takes `LiveBundleIndex`, and then we could make all of these sites slightly less verbose.
