NaplesPU.td

The NaplesPU.td file contains the definition of the Target class NaplesPU (defined in "compiler/include/llvm/Target/Target.td"). The file also contains the definition of the NaplesPUInstrInfo, NaplesPUAsmParser and NaplesPUAsmWriter required by the Target class. In addition, we avoid using instruction itineraries for scheduling. Itineraries are details reservation tables for each instruction class.
