Fix a few tests that were missing ':' on CHECK lines and weren't testing anything. Found by `git grep '\/\/ CHECK-[^: ]* ' clang/test/ | grep -v RUN:`. Also tweak CodeGenCXX/arm-swiftcall.cpp to still pass now that it checks more. Differential Revision: https://reviews.llvm.org/D58061 llvm-svn: 353744

[gnustep-objc] Make the GNUstep v2 ABI work for Windows DLLs. Summary: Based on a patch by Dustin Howett, modified to not change the ABI for ELF platforms. Use more Windows-like section names. This also makes things more readable by PE/COFF debug tools that assume sections fit in the first header. With these changes in, it is now possible to build a working WinObjC with clang and the WinObjC version of GNUstep libobjc (upstream GNUstep libobjc + a work around for incremental linking, which can be removed once LINK.EXE gains a feature to opt sections out of receiving extra padding during an incremental link).
