arch,sim: Add a byteOrder accessor to the Workload class.
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.
