complicated cases like "s&; thread n; s&", and one of
those steps spawning a new thread, and that thread
hitting a breakpoint? It's impossible in general to
track whether the thread had any relation to the commands
that had been executed. So we just simplify and always
mirror breakpoints and random events to the console.
Also, CLI execution commands (-interpreter-exec console
"next", for example) in async mode have the opposite
issue as described in the "then" branch above --
normal_stop has already printed frame information to MI
uiout, but nothing has printed the same information to
the CLI channel. We should print the source line to the
console when stepping or other similar commands, iff the
