sim: delete dead current_state globals
The global current_state handle to the current simulator state is a design idea that was half implemented, but never really cleaned up. The point was to have a global variable pointing to the state so that funcs could more quickly & easily access the state anywhere. We've instead moved in the direction of passing state around everywhere and don't have any intention of moving back. I also can't find any references to gdb using this variable, or to cgen related "dump_regs" functions, both of which were used in the comments related to this code.
