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.
