-In particular, the two compares (marked 1) could be shared by reversing one.
-This could be done in the dag combiner, by swapping a BR_CC when a SETCC of the
-same operands (but backwards) exists.  In this case, this wouldn't save us 
-anything though, because the compares still wouldn't be shared.

 Fold add and sub with constant into non-extern, non-weak addresses so this:
