Linus Groh 6ca03b915e Kernel: Support all Intel-defined CPUID feature flags for EAX=1 ...

We're now able to detect all the regular CPUID feature flags from
ECX/EDX for EAX=1 :^)

None of the new ones are being used for anything yet, but they will show
up in /proc/cpuinfo and subsequently lscpu and SystemMonitor.

Note that I replaced the periods from the SSE 4.1 and 4.2 instructions
with underscores, which matches the internal enum names, Linux's
/proc/cpuinfo and the general pattern of replacing special characters
with underscores to limit feature names to [a-z0-9_].

The enum member stringification has been moved to a new function for
better re-usability and to avoid cluttering up Processor.cpp.
