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

Automatic Reference Counting. Language-design credit goes to a lot of people, but I particularly want to single out Blaine Garst and Patrick Beard for their contributions. Compiler implementation credit goes to Argyrios, Doug, Fariborz, and myself, in no particular order. llvm-svn: 133103

Add the ability to define "fake" arguments on attributes. Fake arguments are automatically handled for serialization, cloning, and other representational tasks, but aren't included in pretty-printing or parsing (should we eventually ever automate that). This is chiefly useful for attributes that can be written by the user, but which are also frequently synthesized by the compiler, and which we'd like to remember details of the synthesis for. As a simple example, use this to narrow the cases in which we were generating a specialized note for implicitly unavailable declarations. llvm-svn: 251469
