[IA64] unwind did not work for processes born with CLONE_STOPPED
Minor problem for mainstream. Big problem for checkpoint/restore, because all the stopped/traced processes are born in this state, hence they cannot be checkpointed again due to failing unwind. The problem was identified as assumption in kernel unwind library that top level frame is different of syscall frame. It is the case unless process was born with CLONE_STOPPED.
