I went back and forth on this one, but eventually decided that that 
ability to bootstrap llvm-gcc on a major platform is more important than 
avoiding a (very cute and well crafted) little hack.  I checked in the 
patch, we can revert it when the real fix for PR1521 is done.

I also wrote a detailed description of the proposed fix for PR1521 in the 
bug if anyone is interested.  The fix would dramatically improve codegen 
quality for structs passed by value (e.g. structs with vectors in them, 
complex numbers, etc), in addition to fixing the correctness problem.
