Florian Hahn 5f8cf84ae0 Recommit "[PatternMatch] Match XOR variant of unsigned-add overflow check." 
This version fixes a buildbot failure cause by picking the wrong insert
point for XORs. We cannot pick the XOR binary operator as insert point,
as it is not guaranteed that both input operands for the overflow
intrinsic are defined before it.

This reverts the revert commit
c7fc0e5da6c3c36eb5f3a874a6cdeaedb26856e0.
