Ah, I forgot to mention that the error was also reproducible using an existing test (the one in clang/test/CodeGenCXX/mangle-nttp-anon-union.cpp).  The specific case that I mentioned ("_Z5dummyIXtl8wrapper1IdEtlNS1_Ut_Edi9RightNametlNS2_Ut_ELd405ec00000000000EEEEEEvv") is just a subset of the mangle-nttp-anon-union.cpp test, specifically the lines below:

  dummy<wrapper1<double>{123.0}>();
  // CHECK: call void @_Z5dummyIXtl8wrapper1IdEtlNS1_Ut_Edi9RightNametlNS2_Ut_ELd405ec00000000000EEEEEEvv
  // DEMANGLED: call void @void dummy<wrapper1<double>{wrapper1<double>::'unnamed'{.RightName = wrapper1<double>::'unnamed'::'unnamed'{0x1.ec{{.*}}p+6}}}>()()
