Strange start line numbers for AST_IF elements

[TysonAndre]

For the below code, with ast VERSION 40 (or 30)

<?php
if (true) {

} else {
}

AST_STMT_LIST @ 1
    0: AST_IF @ 4
        0: AST_IF_ELEM @ 2
            cond: AST_CONST @ 2
                name: AST_NAME @ 2
                    flags: NAME_NOT_FQ (1)
                    name: "true"
            stmts: AST_STMT_LIST @ 2
        1: AST_IF_ELEM @ 4
            cond: null
            stmts: AST_STMT_LIST @ 4

Observed: The line number of AST_IF is 4. The line number of the first AST_IF_ELEM below it is 2.
Expected: The line number of AST_IF should be 2 (4 doesn't make sense as a starting line number)

Fixed upstream with php/php-src@183cd04. In this particular case, the end line of the first element in the list was assigned.
