The workload would have a better idea of what it's endianness is than the system object that holds it. This is the first step towards getting rid of the getByteOrder method on the system object, which currently checks TARGET_ISA to determine what the default endianness should be. If it makes sense for a Workload, it could determine the endianness dynamically by, for instance, reading it out of a binary image before putting it into memory. This does assume that the workload has a consistent endianness throughout which may not be true, but this is not a new assumption. Also, mark the SEWorkload SimObject class as "abstract", since it isn't useful until they get subclassed by some arch specific version.
