Change subject: arch,base,sim: Move GDB stub creation into the arch
Workloads.
......................................................................
arch,base,sim: Move GDB stub creation into the arch Workloads.
These classes know what flavor of GDB stub they want, so there's no need
for TheISA:: to multiplex.
