record: signal a record goto stop to front-ends
The "record goto" command does not indicate the stop to front-ends. Instead,
it prints the new location directly.
Add a function to signal a normal stop to observers and have them print the new
location. This function temporarily switches to the stopped thread.
We use the TARGET_WAITKIND_NO_RESUMED wait status for this purpose. This should
result in a stop notification without giving a stop reason. We could also
invent a new wait status but this doesn't seem necessary at this point.
