reduced test case

clang 13.0.0-rc4 crashes with "Assertion
`getContext().hasSameUnqualifiedType(E->getType(), E->getArg(0)->getType())'
failed." on this sample code:

$ cat bug.ii
class a {
public:
  a();
  a(a &);
  a(int);
  template <typename b> operator b();
};
a c() {
  if (0)
    return a();
  a d;
  return d;
}

$ clang++ bug.ii
clang-13:
/builddir/build/BUILD/llvm-project-release-13.x/clang/lib/CodeGen/CGExprCXX.cpp:616:
void clang::CodeGen::CodeGenFunction::EmitCXXConstructExpr(const
clang::CXXConstructExpr *, clang::CodeGen::AggValueSlot): Assertion
`getContext().hasSameUnqualifiedType(E->getType(), E->getArg(0)->getType())'
failed.
