Previously looking up an extension would result in all extensions for types with the same name (nested or not) being deserialized; this could even bring in base types that had not been deserialized yet. Add in a string to distinguish an extension's base type; in the top-level case this is just a module name, but for nested types it's a full mangled name. This is a little heavier than I'd like it to be, since it means we mangle names and then throw them away, and since it means there's a whole bunch of extra string data in the module just for uniquely identifying a declaration. But it's correct, and does less work than before, and fixes a circularity issue with a nested type A.B.A that apparently used to work. https://bugs.swift.org/browse/SR-3915
