Machine-dependent register-related stuff

allocatableRegs :: [RegNo]

argRegs :: RegNo -> [Reg]

allArgRegs :: [Reg]

callClobberedRegs :: [Reg]

allocatableRegsInClass :: RegClass -> Int

The number of regs in each class. We go via top level CAFs to ensure that we're not recomputing the length of these lists each time the fn is called.
