Nikita Popov 0691e7a8e1 Fix JMPZ, JMPZNZ_EX chain optimization 
The result_type was not copied, resulting in a corrupted JMPZ_EX.
Fix can be verified by inspecting the opcodes of the following
function (it should not contain any _EX opcodes):

function test() {
    if ($a && $b) {
        echo "a";
    }

    if ($b || $c || $d) {
        echo "b";
    }
}
