i386: add KnightsMill cpu model 



A new cpu model called "KnightsMill" is added to model Knights Mill
processors.  Compared to "Skylake-Server" cpu model, the following
features are added:

	avx512_4vnniw avx512_4fmaps avx512pf avx512er avx512_vpopcntdq

and the following features are removed:

	pcid invpcid clflushopt avx512dq avx512bw clwb smap rtm mpx
	xsavec xgetbv1 hle
