fhandler_proc.cc(format_proc_cpuinfo): use feature test print macro
Add feature test print macro that makes feature, bit, and flag text comparison and checking easier. Handle as common former Intel only feature flags also supported on AMD. Change order and some flag names to agree with current Linux.
