The one scenario I can think of where this might do the wrong thing is:

1. Hit breakpoint location 1.1 on thread A
2. Switch to thread B
3. Run a function on thread B, has to only run on thread B and has to actually run code in the target, like:

  (lldb) expr -a 0 -- (int) printf("Hello\n")

The stop reason for thread A should still stay "breakpoint 1.1" and not "no reason".

This one is a little tricky because we have to run the target to execute the function, but if running the expression didn't cause other threads to run, we don't want to lose the program state when we stopped.

I looked for a test that ensures this result, and didn't find one, so I just added one: TestStateAfterExpression.py.  Can you make sure that your change still passes this test.  If it does, I can't think of anything else that might go wrong with this patch.
