[PATCH] Fix addrspace when emitting constructors of static local variables

Interesting, clang crashes if StructWithCtor has a dtor. However, as far as I can see, it is a separate issue unrelated to address space casting and should be fixed in another patch. In this version, I only tested the default contructor, the copy constructor and a regular member function.

FYI, the call stack if I add the dtor:
