LiftoffRegister is an abstraction over Register and DoubleRegister. Many functions in Liftoff do not need to distinguish GP and FP registers. LiftoffRegister allows to implement most functions generically. Accessors allow to convert them back to Register or DoubleRegister. Both register types are represented in a unified index space, which allows to extend this concept to more register types and implement aliasing in a straight-forward manner. Many functions currently only implement the GP case. FP will be added later.
