[PATCH v3 5/5] x86: short-circuit certain cpu_has_* when x86-64-v{2,3} are in effect

Certain fallback code can be made subject to DCE this way. Note that CX16 has no compiler provided manifest constant, so CONFIG_* are used there instead. Note also that we don't have cpu_has_movbe nor cpu_has_lzcnt (aka cpu_has_abm). Signed-off-by: Jan Beulich --- Of course we could use
