Hahnfeld created this revision.
Hahnfeld added reviewers: ABataev, hfinkel, carlo.bertolli, sfantao.
Hahnfeld added a subscriber: cfe-commits.
Pointer dereference is equal to access of first array element which is already
allowed for the `reduction` clause.
While at it also add test for CodeGen of reduction on array element which
seemed to be missing.
