Mircea Trofin 73b96d6dcf [LV] Fix analyzeInterleaving when -pass-remarks enabled 
Summary:
If -pass-remarks=loop-vectorize, atomic ops will be seen by
analyzeInterleaving(), even though canVectorizeMemory() == false. This
is because we are requesting extra analysis instead of bailing out.

In such a case, we end up with a Group in both Load- and StoreGroups,
and then we'll try to access freed memory when traversing LoadGroups after having had released the Group when  iterating over StoreGroups.

The fix is to include mayWriteToMemory() when validating that two
instructions are the same kind of memory operation.
