Stephen Kelly 0df805db73 [ASTDump] Add utility for dumping a label with child nodes
Summary:
Use it to add optional label nodes to Stmt dumps.  This preserves
behavior of InitExprList dump:

// CHECK-NEXT: `-InitListExpr {{.+}} <col:13, col:15> 'U [3]'
// CHECK-NEXT:   |-array_filler: InitListExpr {{.+}} <col:15> 'U' field Field {{.+}} 'i' 'int'
// CHECK-NEXT:   `-InitListExpr {{.+}} <col:14> 'U' field Field {{.+}} 'i' 'int'
// CHECK-NEXT:     `-IntegerLiteral {{.+}} <col:14> 'int' 1
