  Changed paths:
    M clang/lib/Index/IndexDecl.cpp
    A clang/test/Index/using_if_exists.cpp

  Log Message:
  [Index] Remove reference to `UnresolvedUsingIfExists`

Assuming `ns::foo` doesn't exist, given:
using ns::foo __attribute__((using_if_exists));

The AST will look something like:

Thus we end up adding a reference to `UnresolvedUsingIfExistsDecl` when
processing `UsingDecl`, but never add the decl itself. In this case the
decl is really the `UsingDecl` anyway though (which we do output), so it
makes more sense to just remove the extra reference.
