Bug 14300 – [2.067-rc1] DList casting to base type is broken

Worked on 2.066, but new release candidate fails. Code: ``` import std.container.dlist; interface ITest {} class Test : ITest {} void main() { DList!ITest().insertBack(new Test()); } ``` Output: ``` /usr/include/dmd/phobos/std/container/dlist.d(642): Error: template std.container.dlist.DList!(ITest).DList.createNode cannot deduce function from argument types !()(Test, BaseNode*, BaseNode*), candidates are: /usr/include/dmd/phobos/std/container/dlist.d(166): std.container.dlist.DList!(ITest).DList.createNode()(ref T arg, BaseNode* prev = null, BaseNode* next = null) /usr/include/dmd/phobos/std/container/dlist.d(414): Error: template instance std.container.dlist.DList!(ITest).DList.insertBeforeNode!(Test) error instantiating source/app.d(9): instantiated from here: insertBack!(Test) ```
