Documentation
classOfReg :: Reg -> RegClass
Determine the class of a register
regsOfClass :: RegClass -> UniqSet Reg

regName :: Reg -> Maybe String
Determine the common name of a reg returns Nothing if this reg is not part of the machine.
regAlias :: Reg -> UniqSet Reg
Which regs alias what other regs
worst :: Int -> RegClass -> RegClass -> Int
