  This is a repost of my brute-force CPUID dumper for the x86
architectures.

Adhemerval, do you still have concerns about this?  I think we need this
diagnostic aid somewhere, so that people can figure out why their IFUNC
resolvers etc. are not working as expected.

We have a request for adding some AArch64 diagnostic data, too, although
it is going to be much less.

Thanks,
Florian
