The output IR as pasted can't be improved upon. 
@_D5temp216__T9factorialTiZ9factorialFiZi and 
@_D5temp216__T9factorialTkZ9factorialFkZk are weak, so there's nothing more to
do. We can't delete them (since they're externally visible symbols) or merge
them any further since they contain nothing but calls to @0. @0 places calls to
both of the @_D5temp... methods, but since those are weak, we can't turn those
into direct calls of @0 either.
