This commit changes the 'skip' method in the 'KeyValueNode' class to ensure that it doesn't dereference a null pointer when calling the 'skip' method of its value child node. It also adds a unittest that ensures that the crash doesn't occur. This change is motivated by a patch that implements parsing of YAML block scalars (http://reviews.llvm.org/D9503), as one of the unittests in that patch triggered this problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@236669 91177308-0d34-0410-b5e6-96231b3b80d8
