Make -fobjc-nonfragile-abi the -cc1 default, since it's the increasingly prevailing case to the point that new features like ARC don't even support the fragile ABI anymore. This required a little bit of reshuffling with exceptions because a check was assuming that ObjCNonFragileABI was only being set in ObjC mode, and that's actually a bit obnoxious to do. Most, though, it involved a perl script to translate a ton of test cases. Mostly no functionality change for driver users, although there are corner cases with disabling language-specific exceptions that we should handle more correctly now. llvm-svn: 140957

Eliminate &&s in tests. - 'for i in $(find . -type f); do sed -e 's#\(RUN:.*[^ ]\) *&& *$#\1#g' $i | FileUpdate $i; done', for the curious. llvm-svn: 86430

Patch fixes an obscure bug when 'used' attribute is applied to variables in ObjC's Next runtime mode. Next runtime also implicitly applies 'used' attribute on some of its meta-data. This results in two 'llvm.used' arrays to be generated, and one of them is renamed to 'llvm.used1'. llvm-svn: 74008
