Doug Gregor c367c8e9cb [Runtime] Adjust "conforming type" based on a given conformance descriptor. ...

When we are looking for the specific type for a protocol conformance (e.g.,
because we may have a subclass of the type that declared conformances), don't
go back through swift_conformsToProtocol() multiple times, which
requires more lookups in the global conformance table. Instead, use
the (known) protocol conformance descriptor.
