The ARM Target doesn't use the class CCState. For example,
CCState.AnalyzeCallOperands, CCState.AnalyzeCallReturn,
CCState.AnalyzeReturn, etc. There is no ARMCallingConv.td as there is
for other targets. All calling convention decisions are made manually.

If there is no reason not to, it might simplify adding the AAPCS
Standard Variants like AAPCS-AFP, etc. since they'll be defined with
TableGen and therefore more readily extended.
