Testcase
Instead of a new value the copy of the scalar %cmp in the non-affine region
uses the original PHI node %height.lcsssa. __Later__ the PHI node is copied and
assumed to escape as there is a user not in the region (namely the copied
%cmp). The problem seems to be a missing scalar access in the non-affine region
or at least a mapping that would use a reloaded value not the original PHI.</pre>
