LOG: [X86] Add AMD Llano family detection (#111312)

Very simple one liner, adds the missing detection for the Llano family
which is essentially a refreshed K10:
Documentation of the family id:
https://en.wikichip.org/wiki/amd/cpuid#Family_18_.2812h.29
Documentation that it fits into amdfam10:
https://en.wikipedia.org/wiki/AMD_10h#12h

Added: 
    

Modified: 
    compiler-rt/lib/builtins/cpu_model/x86.c
    llvm/lib/TargetParser/Host.cpp

Removed:
