This reverts commit r263607.

This change caused more objc_retain/objc_release calls in the IR but those
are then incorrectly optimized by the ARC optimizer.  Work is going to have
to be done to ensure the ARC optimizer doesn't optimize user written RR, but
that should land before this change.

This change will also need to be updated to take account for any changes required
to ensure that user written calls to RR are distinct from those inserted by ARC.

// C Language Family Front-end
//===----------------------------------------------------------------------===//

Welcome to Clang.  This is a compiler front-end for the C family of languages
(C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM
compiler infrastructure project.

Unlike many other compiler frontends, Clang is useful for a number of things
beyond just compiling code: we intend for Clang to be host to a number of
different source-level tools.  One example of this is the Clang Static Analyzer.

If you're interested in more (including how to build Clang) it is best to read
the relevant web sites.  Here are some pointers:
