78e9aa70fe sim: unify sim-cpu usage
Now that all the targets are utilizing CPU_PC_{FETCH,STORE}, and the
cpu state is multicore, and the STATE_CPU defines match, we can move
it all to the common code.

523ba8f92e sim: erc32/h8300/m68hc11: trim unused functions
These funcs are only used with the old run.o, and these sims use nrun.o,
so drop these stub funcs.

8acc9f485b Update years in copyright notice for the GDB files.
Two modifications:
  1. The addition of 2013 to the copyright year range for every file;
  2. The use of a single year range, instead of potentially multiple
     year ranges, as approved by the FSF.
