[MS ABI] Assign an inheritance model for the dest of a member pointer upcast While we correctly assigned an inheritance model for the source of a member pointer upcast, we did not do so for the destination. This fixes PR27030. llvm-svn: 264065

// RUN: %clang_cc1 -emit-llvm -triple=i386-pc-win32 %s -o - | FileCheck %s
struct A {};
struct B : A {};
extern "C" {
extern int B::*a;
void test1() { (int A::*)(a); }
}
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
