Cherry Mui 8c73f80400 runtime: bypass scheduler when doing traceback for goroutine profile 
When acquire a goroutine profile, we stop the world then acquire a
stack trace for each goroutine. When cgo traceback is used, the
traceback code may call the cgo traceback function using cgocall.
As the world is stopped, cgocall will be blocked at exitsyscall,
causing a deadlock. Bypass the scheduler (using asmcgocall) to fix
this.
