This patch adds a the member function StaticInst::printFlags to allow all of an instruction's flags to be printed without using the individual is... member functions or resorting to exposing the 'flags' vector It also replaces the enum definition StaticInst::Flags with a Python-generated enumeration and adds to the enum generation mechanism in src/python/m5/params.py to allow Enums to be placed in namespaces other than Enums or, alternatively, in wrapper structs allowing them to be inherited by other classes (so populating that class's name-space with the enumeration element names).
