function exitLabeledStatement(node) {
			if (!astUtils.isBreakableStatement(node.body)) {
				scopeInfo = scopeInfo.upper;
			}
		}

This ignores it if the body is a breakable statement.
In this case it's handled in the `exitBreakableStatement` function.
@param {ASTNode} node A node. This is a LabeledStatement.
@returns {void}
