Fix a trivial oversight with apple-kext static local destructors and add a test case. llvm-svn: 154653

// RUN: %clang_cc1 -triple x86_64-apple-darwin10 -fno-use-cxa-atexit -fapple-kext -emit-llvm -o - %s | FileCheck %s
// CHECK: @_ZN5test01aE = global [[A:%.*]] zeroinitializer
Use comdats to avoid double initialization of weak data Initializers of global data that can appear multiple TUs (static data members of class templates or __declspec(selectany) data) are now in a comdat group keyed on the global variable being initialized. On non-Windows platforms, this is a code size and startup time optimization. On Windows, this is necessary for ABI compatibility with MSVC. Fixes PR16959.
