Auto merge of #49472 - nikomatsakis:nll-optimize-constraint-prop-1, r=pnkfelix
optimize NLL constraint propagation a little Removes a bone-headed hot spot in NLL constant propagation; we were re-allocating the stack vector and hashmap as we repeated the DFS. This change shares those resources across each call. It also modifies the constraint list to be a linked list; arguably I should revert that, though, as this didn't turn out to be a perf hit and perhaps the old code was clearer? (Still, the new style appeals to me.) r? @pnkfelix
