[PATCH] D36425: [ZoneAlgo] Allow two writes that write identical values into same array slot

[Tobias Grosser via Phabricator via llvm-commits]

Two write statements which write into the very same array slot generally are
conflicting. However, in case the value that is written is identical, this
does not cause any problem. Hence, allow such write pairs in this specific
situation.
