The more awkward setup with pushGenericParams()/popGenericParams() is required so that when demangling requirements and field types we get the correct pack-ness for each type parameter. The pack-ness is encoded as part of the generic signature, and not as part of the type parameter mangling itself. Fixes the ASTDemangler issue from rdar://problem/115459973.
