It is better to check if some older cpu models like 486, athlon, pentium,
penryn, phenom, core2duo etc are available before running their corresponding
tests. Some downstream distributions may no longer support these older cpu
models.
One minor correction. Replaced 'phenom' with '486' in the test
'x86/cpuid/auto-level/phenom/arat' matching the cpu used.
