Damien Neil 049a5e6036 runtime: return a different bubble deadlock error when main goroutine is done 
The synctest.Test function waits for all goroutines in a bubble to
exit before returning. If there is ever a point when all goroutines
in a bubble are durably blocked, it panics and reports a deadlock.

Panic with a different message depending on whether the bubble's
main goroutine has returned or not. The main goroutine returning
stops the bubble clock, so knowing whether it is running or not
is useful debugging information.

The new panic messages are:
	deadlock: all goroutines in bubble are blocked
	deadlock: main bubble goroutine has exited but blocked goroutines remain
