Issues with assembly function declarations

[area]

There seems to be an issue with Assembly Function Declarations. All of the following are valid according to remix, but this parser seems to only successfully parse the first one:

pragma solidity ^0.5.0;

contract JoinSplit {
    function() external payable {
        assembly {
            function validateJoinSplit(y) -> x {

            }
        }
    }
}

pragma solidity ^0.5.0;

contract JoinSplit {
    function() external payable {
        assembly {
            function validateJoinSplit(y) {

            }
        }
    }
}

pragma solidity ^0.5.0;

contract JoinSplit {
    function() external payable {
        assembly {
            function validateJoinSplit() -> x {

            }
        }
    }
}

Thanks for reporting this! It should be fixed in latest master. I will cut a release in the next few days.
