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 2011-10-02 09:16:38 +08:00			`// RUN: %clang_cc1 -triple x86_64-apple-darwin9 -fobjc-fragile-abi -fobjc-gc -emit-llvm -o %t %s`
