LOG: [X86] Add family/model for Intel Comet Lake CPUs for -march=native and function multiversioning

This adds the family/model returned by CPUID for some Intel
Comet Lake CPUs. Instruction set and tuning wise these are
the same as "skylake".

These are not in the Intel SDM yet, but these should be correct.
