variant4 from common.c::cpu_no_spec_store_bypass

Variant 4 - Add function to 'whitelist' the hand-full of CPUs unaffected by speculative store bypass.
This would allow improved determination of variant 4 status ( #189 ) of immune CPUs while waiting for the 4.17/stable patches to be backported to distro kernels.

ibrs can't be enabled on no ibrs cpu ( #195 )
...
* ibrs can't be enabled on no ibrs cpu
If the cpu is identified, and does not support SPEC_CTRL or IBRS, then ibrs can't be enabled, even if supported by the kernel.
Instead of reporting IBRS enabled and active UNKNOWN, report IBRS enabled and active NO.
