df0fe27b66 Fixup the rest of the trivial cases of the codegen of volatile. If 
any body can spot codegen bugs with volatile, or knows of any in the
bug database, let me know.

2a69547f38 PR4281: Fix bogus CodeGen assertion. The issue is that 
getUnqualifiedType() doesn't strip off all qualifiers for non-canonical 
types.

one else is tempted to copy the style, incorrectly.

1518b64ddc When trying to pass an argument on the stack, assume LLVM will do the right 
thing for non-aggregate types.
 - Otherwise we unnecessarily pin values to the stack and currently end up
   triggering a backend bug in one case.

 - This loose cooperation with LLVM to implement the ABI is pretty ugly.

a4404f21d1 This patch adds support for sender-aware dispatch in Objective-C for the GNU runtime, when 
compiled with -fobjc-sender-dependent-dispatch.  This is used in AOP, COP, implementing object 
planes, and a few other things.

aed08f9929 Fixup blocks codegen for { __block i; i = rhs(); }, we want the rhs 
evaluated first.  This can also improve codegen just a bit as we might
have another register to play with for the evaluation of the rhs.

d20a03f308 This patch provides preliminary support for non-fragile instance variables on the GNU runtime. 
It currently requires a patches to GNU libobjc (and so is not enabled by default) which are currently 
being tested and reviewed by GNUstep before being pushed upstream.
This patch does not allow support for synthesized ivars, but does provide the infrastructure 
needed for supporting them.

c21cb44de2 Handle the remaining unhandled cases in EmitReferenceBindingToExpr. 
It would be nice if someone could write an ObjC++ testcase for the case 
of passing a property returning a struct to a function taking a const
reference.
