[clang][Index] Mark references from Constructors and Destructors to class as NameReference

Summary:
In current indexing logic we get references to class itself when we see
a constructor/destructor which is only syntactically true. Semantically
this information is not correct. This patch marks that reference as
NameReference to let clients deal with it.
