cmake: Add new Intel CPU model numbers
cmake: Add new Intel CPU model numbers

A new Intel ORM was released, containing four new CPU model numbers.
This also introduces Skylake. At this point there's no support for
AVX-512 in Vc anyway, but this seems to be a little harder to determine
just from the model number alone.
