CodeGen: tweak CFString emission for COFF targets The `isa' member was previously not given the correct DLL Storage. Ensure that we give the `isa' constant `__CFConstantStringClassReference' the correct DLL storage. Default to dllimport unless an explicit specification gives it a dllexport storage. llvm-svn: 271361

Set dso_local for CFConstantStringClassReference. This one cannot use setGVProperties since it has special logic for when it is dllimport or not. llvm-svn: 327993

// CHECK-CF-IN-CF-DECL: @__CFConstantStringClassReference = external dso_local dllexport global [0 x i32]
Bring r325915 back. The tests that failed on a windows host have been fixed. Original message: Start setting dso_local for COFF. With this there are still some GVs where we don't set dso_local because setGVProperties is never called. I intend to fix that in followup commits. This is just the bare minimum to teach shouldAssumeDSOLocal what it should do for COFF. llvm-svn: 325940
