  Log Message:
  -----------
  Fix the DeclContextLookupResult::iterator non-copyable.

The value_type is a const pointer, which makes the iteator non-copyable.
Before the patch, the normal usage like below was illegal:

```
auto It = lookupresult.begin();
...
It = lookupresult.end(); // the copy is not allowed.
```
