  Log Message:
  -----------
  Linker: Disallow linking appending globals with different addrspaces

The current appending linkage handling implicitly assumes this by
using a basic ConstantExpr::getBitCast to resolve type
mismatches. Avoid this edge case so we don't need to keep the type
mismatch replacement code around after opaque pointers.
