Revised testcase without confusing casts
This changes the testcase to not cast int* to Loc<1>*, but use Loc<1>[2] as
storage for Loc<2> while retaining the initialization properties. It requires
the testcase be compiled with tree-level loop-unrolling enabled, as the empty
constructors/destructors for array members are created as loops by the C++
frontend.
Other than that, struct aliasing (or just removing the casts) doesn't fix the
aliasing problems - though struct aliasing doesn't handle array elements at
the moment(?).
