References to different declarations of the same entity aren't different values, so shouldn't have different representations. Recommit of e6393ee813178e9d3306b8e3c6949a4f32f8a2cb, most recently reverted in 9a33f027ac7d73e14ae287e78ab554142d1cbc8f due to a bug caused by ObjCInterfaceDecls not propagating availability attributes along their redeclaration chains; that bug was fixed in e2d4174e9c66251d1b408234b53f53d0903c0285.
