Move op_class.hh out of encumbered/cpu/full and into cpu.

Pull opClassStrings array out of encumbered/cpu/full/fu_pool.cc and move to
new cpu/op_class.cc file.

SConscript:
    Add new cpu-model-independent file to define OpClass enum strings.
cpu/op_class.hh:
    Fix comments etc.
cpu/static_inst.hh:
    op_class.hh moved to cpu directory

rename : encumbered/cpu/full/op_class.hh => cpu/op_class.hh
