Refactor ObjC conflict diagnosis code to sort conflict data more thoroughly, filter out unwanted declarations earlier, and just generally behave in ways that are more likely to work correctly. This change increases the determinism of the ordering of diagnostics and the selection of the “correct” declaration that the others are considered to conflict with, increasing my confidence that the diagnostics will work correctly in untested corner cases or if the compiler is refactored so that declarations are recorded in a different order. It also adds a new selection rule—@objc without vs. with explicit selector—that I believe will slightly improve the diagnostics we produce. And it replaces a lot of really dodgy-looking logic that may have only worked reliably when a conflict involved exactly two methods.
