    Original Commit Message:
    
        Modernise the RegList interface to be a proper class, rather than a
        typedef to an integer, and add proper methods onto it rather than ad-hoc
        bit manipulation.
    
        In particular, this makes RegList typesafe, adding a DoubleRegList for
        DoubleRegisters.
    
        The Arm64 CPURegList isn't updated to use (or extend) the new RegList
        interface, because of its weird type-erasing semantics (it can store
        Registers and VRegisters). Maybe in the future we'll want to get rid of
        CPURegList entirely and use RegList/DoubleRegList directly.
