Add llvm.xcore.waitevent intrinsic. The effect of this intrinsic is to enable events on the thread and wait until a resource is ready to event. The vector of the resource that is ready is returned. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126320 91177308-0d34-0410-b5e6-96231b3b80d8

Add checkevent intrinsic to check if any resources owned by the current thread can event. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127741 91177308-0d34-0410-b5e6-96231b3b80d8
