When a typealias or associated type is declared inside a protocol, the
mangling of an access like S.A (for `typealias A` in `protocol P` and
`struct S : P`) wraps the protocol in a BoundGenericProtocol whose
single generic argument is the conforming Self type:
BoundGenericProtocol
|
--> Protocol: P
|
--> TypeList:
|
--> Structure: S
DemanglingForTypeRef was substituting the richer parent wholesale in
place of the Protocol, losing the BoundGenericProtocol entirely and
producing a mangled tree that looks as if A were declared directly
on S rather than inside P.
