Ian Lance Taylor f6be1179bb runtime: prevent deadlock when profiling signal arrives during traceback ... Traceback routines, e.g. callers and funcentry, may call __go_get_backtrace_state. If a profiling signal arrives while we are in the critical section of __go_get_backtrace_state, it tries to do a traceback, which also calls __go_get_backtrace_state, which tries to enter the same critical section and will deadlock. Prevent this deadlock by setting up runtime_in_callers before calling __go_get_backtrace_state. Found while investigating golang/go#29448. Will add a test in the next CL. Updates golang/go#29448.
