Doug Gregor 8bd093d36b Eliminate the "ambiguous implied conformance" error.
Instead of requiring the user to disambiguate where an implied
protocol conformance goes---which they really, really don't care
about---just pick an arbitrary-but-deterministic location for the
conformance, which corresponds to the file unit in which the witness
table will be emitted. Fixes rdar://problem/21538899.
