Subject: Created new M5 instruction to allow an integer parameter (init_param)
 to be specified in the INI and then read inside the simulator.

arch/alpha/isa_desc:
    Added new M5FUNC instruction to put allow reading of init_param inside simulator
kern/tru64/tru64_system.cc:
kern/tru64/tru64_system.hh:
sim/system.cc:
sim/system.hh:
    Added support for init_param
