  [DSE] Make iter order deterministic in removePartiallyOverlappedStores. NFC (#127678)

In removePartiallyOverlappedStores we iterate over
InstOverlapIntervalsTy which is a DenseMap. Change that map into using
MapVector to ensure that we apply the transforms in a deterministic
order. I've only seen that the order matters if starting to use names
for the instructions created when doing the transforms. But such things
are a bit annoying when debugging etc.
