Mike Ash 6473b9d7cd [Runtime] Fix swift_conformsToProtocol crashing on conformances to unavailable classes. 
An extension on a class creates a conformance record that's always visible even when that class is not present at runtime. In that case, the type pointer in the conformance record is NULL. The runtime did not like this, and crashed. This fixes it to ignore such records instead.
