rose: move END instruction to start of enum

Browse Source 
Stop overloading END as the last Rose interpreter instruction, use new
sentinel LAST_ROSE_INSTRUCTION for that.

This change will also make it easier to add new instructions without
renumbering END and thus changing all generated bytecodes.
