When we notice that a type implicitly conforms to a protocol but is
not explicitly stated to do so, note this and provide a Fix-It
attaching the conformance to a declaration within the translation
unit, e.g.,
t.swift:28:16: error: type 'S1' does not explicitly conform to protocol 'P'
var p1 : P = S1()
^
t.swift:8:8: note: introduce explicit conformance to protocol 'P'
struct S1 : Q {
^
, P

This makes ProtocolConformances fully self-identifying so that a ProtocolConformance* pointer alone is enough to identify a conformance as a link entity.
We currently lose the conforming decl during deserialization because trying to deserialize a reference to an ExtensionDecl asserts out. I'll bug Jordan about that.

Previously, we only tracked the mapping from associated types to their
type witnesses. Now, also track the protocol conformances for each of
the requirements placed on the associated types.
