My changes _are_ backward compatible.  I add five new bytecodes taken from
the unused experimental bytecodes.  The existing bytecodes are still
supported and the VM runs both closures and BlockContext blocks
side-by-side.

I have another VM in the works which does context-to-stack mapping and that
only runs closures.  But I have yet to publish this or the Slang changes
that go with it.
