An extractor class to create and pattern match with syntax
LabelDef(name, params, rhs).This AST node does not have direct correspondence to Scala code. It is used for tailcalls and like. For example, while/do are desugared to label defs as follows:
while (cond) body ==> LabelDef($L, List(), if (cond) { body; L$() } else ())
