What return type and argument type to use would you suggest for this generic function? If it is something like

  i8 addrspace(1)* to_global(i8 addrspace(4)*)

then bitcasts will be needed, which is what we want to avoid.

These functions accept pointers to arbitrary user types, so they cannot be declared in a header file.
