[PATCH] D14737: Convert some ObjC msgSends to runtime calls

[Pete Cooper via cfe-commits]

pete added a comment.

Added a couple of tests for retain returning types other than id.  Returning a pointer should still be converted to a call, while returning a non-pointer such as float will get a message instead.

I walked through the code in the debugger to check on the return cast.  Turns out it is handled at the very end of emitARCValueOperation as follows:

  // Cast the result back to the original type.
  return CGF.Builder.CreateBitCast(call, origType);
