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