[PATCH] D13233: Combining invariant.group metadata bugfix

[Philip Reames via llvm-commits]

If the GVN example is reasonable small, that would be fine.  In general, 
even complex scenarios can be reduced if care is taken to eliminate all 
the redundant pieces.

This code is also exercised by simplify-cfg and instcombine.  You might 
have an easier time constructing a small case from one of those.
