[PATCH] D144486: [Assignment Tracking] Initialise maps with exact required number of entries

I made a mistake saying the exact size is known. This is actually the lower bound of the `Join` map size, since it is possible that the maps _both_ contain unique variables. I'll update the summary and description before landing.
