Work towards factoring isa_traits.hh into smaller, more specialized files.

arch/SConscript:
    Sorted the switch headers, and added registerfile.hh, constants.hh, types.hh, and utility.hh.
arch/alpha/isa_traits.hh:
    Moved the register file types to registerfile.hh, small functions to utility.hh, and cleaned out alot of stuff that isn't necessary anymore.
base/loader/ecoff_object.cc:
base/loader/elf_object.cc:
cpu/pc_event.hh:
cpu/static_inst.hh:
mem/port.hh:
sim/faults.cc:
sim/system.hh:
    base/misc.hh isn't included through isa_traits.hh anymore.
cpu/simple/cpu.cc:
    Added include for arch/utility.hh
