Add clang support for new Objective-C literal syntax for NSDictionary, NSArray, NSNumber, and boolean literals. This includes both Sema and Codegen support. Included is also support for new Objective-C container subscripting. My apologies for the large patch. It was very difficult to break apart. The patch introduces changes to the driver as well to cause clang to link in additional runtime support when needed to support the new language features. Docs are forthcoming to document the implementation and behavior of these features. llvm-svn: 152137

[CodeGen][ObjC] Annotate calls to objc_retainAutoreleasedReturnValue with notail on x86-64. On x86-64, the epilogue code inserted before the tail jump blocks the autoreleased return optimization. rdar://problem/38675807 Differential Revision: https://reviews.llvm.org/D59656 llvm-svn: 356705

At -O0, prefer objc_storeStrong with a null new value to the combination of a load+objc_release; this is generally better for tools that try to track why values are retained and released. Also use objc_storeStrong when copying a block (again, only at -O0), which requires us to do a preliminary store of null in order to compensate for objc_storeStrong's assign semantics. llvm-svn: 166085
