    runtime: never show system goroutines in traceback · 59495e8d

    Fixes #9791
    
    g.issystem flag setup races with other code wherever we set it.
    Even if we set both in parent goroutine and in the system goroutine,
    it is still possible that some other goroutine crashes
    before the flag is set. We could pass issystem flag to newproc1,
    but we start all goroutines with go nowadays.
    
    Instead look at g.startpc to distinguish system goroutines (similar to topofstack).
