bail out of selection when there are multiple surviving candidates
In some cases (e.g. <[int-var] as Add<[int-var]>>), selection can turn up a large number of candidates. Bailing out early avoids O(n^2) performance. This improves item-type checking time by quite a bit, resulting in ~2% of total time-to-typeck.
