This is going to be hard to fix really, unless we make explicate the target's
behavior for passing structs (via value or by reference).
Right now we get:
D.1992 = f () [return slot optimization];
g (D.1992) [tail call];
Which looks ok if we are passing via value but since we need to pass by
reference, the middle-end thinks we need a new stack space for it because it
does not know that D.1992 is not used after the call to g.
