__declspec is not a core Clang language extension. Instead, require -fms-extensions or -fborland to enable the language extension. Note: __declspec is also temporarily enabled when compiling for a CUDA target because there are implementation details relying on __declspec(property) support currently. When those details change, __declspec should be disabled for CUDA targets. llvm-svn: 238238

Makes A Microsoft Layout CodeGen Test Explicit This patch tests introduces a proper codegen test in place of the "codegen no longer crashes" test introduced in r193664. The test is also moved from layout to CodeGenCXX. Differential Revision: http://llvm-reviews.chandlerc.com/D2174 llvm-svn: 194739
