  + Convert the dotest style tests to use lldbutil.run_to_source_breakpoint.
  +
  + <p>
  + run_to_source_breakpoint & run_to_name_breakpoint provide a compact API that
  + does in one line what the first 10 or 20 lines of most of the old tests now do by
  + hand. Using these functions makes tests much more readable, and by centralizing
  + common functionality will make maintaining the testsuites easier in the future.
  + This is more of a finger exercise, and perhaps best implemented by a rule like:
  + &quotIf you touch a test case, and it isn't using run_to_source_breakpoint, please
  + make it do so&quot.

  Unify Watchpoint's & Breakpoints.
