  Log Message:
  -----------
  ProcessorSimulator plugins as per Cog-eem.418
IA32ABI plugin as per VMMaker.oscog-eem.2857

Add the offset version of the run/step primitives
which allow simulation of the simulator.

IA32ABI: make most of the simple acessors simulate.  This makes it possible to
simulate the simulator ;-)

Slang: generate neater code for pointer indirection.  Instead of indexing with
zero, dereference with *.
