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

[ObjC] Allow declaring __strong pointer fields in structs in Objective-C ARC mode. Declaring __strong pointer fields in structs was not allowed in Objective-C ARC until now because that would make the struct non-trivial to default-initialize, copy/move, and destroy, which is not something C was designed to do. This patch lifts that restriction. Special functions for non-trivial C structs are synthesized that are needed to default-initialize, copy/move, and destroy the structs and manage the ownership of the objects the __strong pointer fields point to. Non-trivial structs passed to functions are destructed in the callee function. rdar://problem/33599681 Differential Revision: https://reviews.llvm.org/D41228 llvm-svn: 326307
