sim: delete old breakpoint code
This code relies on the old sim-break module, but that was deleted in 2003. The module only existed for gdb to tell the sim to set breakpoints on its behalf, but then that logic was abandoned in favor of gdb knowing all about proper breakpoints (since it does already for non-sim targets). Some dead code lived on in the older ports though -- clean it up now.
