maybe TREE_ADDRESSABLE is too strong: It generates errors in the
backend if the frontend produces non-lvalues:
---
auto b = Date();
a(b);
---

works, but
---
a(Date());
---

fails in gimplify.c. Do we really have to rewrite such cases so that
non-PODs get a temporary variable? And how would this be done? It seems
we would have to use the frontend for this, as maybeMakeTemp and
makeTemp refuse to work for TREE_ADDRESSABLE types.

Don't set it on the variable, set it on the type.

TypeStruct::toCtype()
{
TYPE_ADDRESSABLE(ctype) = !isPOD();

}
