* Sends a SIGSTOP to the process. * Fixes busted SIGSTOP handling. Now builds a list of non-stopped that we wait for the PTRACE group-stop for. When the final must-stop tid gets its group stop, we propagate the process state change. Only the signal receiving the notification of the pending SIGSTOP is marked with the SIGSTOP signal. All the rest, if they weren't already stopped, are marked as stopped with signal 0. * Fixes a few broken tests. * Marks the Linux test I added earlier as expect-pass (no longer XFAIL). Implements fix for http://llvm.org/bugs/show_bug.cgi?id=20908. llvm-svn: 217647
