Jared Casper 9b785031f5 Implement SystemVerilog final statements. 
Add a new IVL_PR_FINAL process type.

Add a flag to NetScope in_final_ which is set when elaborating the
statement of a final procedure.

Add checks during statement elaboration for invalid statements in a
final procedure, similar to checks for statements in functions.

Do a final check to make sure no final blocks have delays.

In the vvp runtime, use "$final" as the flag for the thread created by
the final procedure.  During compilation, instead of adding such a
thread to the sched_list, add it to a new schedule_final_list that
mirrors the schedule_init_list, but is run at the end of simulation.
