acquired only after checking if the ivar shared pointer was already filled in. But when I assign an UnwindPlan object to the shared pointer, I assign an empty object and then fill it in. That leaves a window where another thread could get the shared pointer to the empty (but quickly being-filled-in) object and lead to a crash. Also two changes from Greg for correctness on the TestMultipleDebuggers test case. <rdar://problem/30564102> llvm-svn: 296084
