Devin Coughlin f239ae2ad7 [Exclusivity] Suggest Fix-Its to replace swap() with swapAt() ...

Extend the static diagnostics for exclusivity violations to suggest replacing

  swap(&collection[index1], &collection[index2]

with

  collection.swapAt(index1, index2).

when 'collection' is a MutableCollection.

To do so, repurpose some vestigial code that was previously used to suppress all
exclusivity diagnostics for calls to swap() and add some additional syntactic,
semantic,  and textual pattern matching.
