This patch fixes the access check for nested private C++ enums to look for the SWIFT_PRIVATE_FILEID of the enclosing C++ class, if any. Previously, the check was looking at for SWIFT_PRIVATE_FILEID on the enum decl itself (which is meaningless); that prevented nested private enum members from being accessible in Swift. This patch also specializes the type signature of getPrivateFileIDAttrs to clarify the fact that SWIFT_PRIVATE_FILEID is not a meaningful annotation on anything other than CXXRecordDecl, because that is the only kind of decl that can assign access specifiers to its members. rdar://148081340
