I would like having a global cpu_name_by_type_name() function.
I wouldn't want to force each architecture to provide yet another
string conversion/parsing function, though.

I think we could do that, but with a CPUClass field instead of a
preprocessor macro.

For a reference on existing corner cases of CPU model name
parsing that might get in the way, see this series:

If you are interested, I have work in progress for a generic CPU
model listing function at:
