Latest edition (039) of "Intel Architecture Instruction Set Extensions
and Future Features Programming Reference" includes three new CPU model
numbers. Linux already has the two Ice Lake server ones. Add the new
model number for Sapphire Rapids.

[marcelo.cerri: adjusted context. intel-family.h had several
 refactors. Sapphire rapids was still add as INTEL_FAM6_, so this
 adjustment is just a matter of ordering the defines.]
