Summary

To build with old toolchains use the *_REG macros to access the ID
registers. These become a name in the form S?_?_C?_C?_? where the '?'
values encode the op and CR values needed to access the register.

For consistency use these macros for all ID registers, even if most
toolchains understand them.
