Improvements to detection of AMD architectures. (#13407)

New entry for K10 microarchitecture.

Reorder Zen* microarchitectures to avoid triggering as k10.

Remove some desktop-specific flags that were preventing Opteron Bulldozer/Piledriver/Steamroller/Excavator CPUs from being recognized as such.

Remove one or two flags which weren't produced in /proc/cpuinfo on older OS (RHEL6 and friends).
