Hide FunctionTemplateDecl's specializations folding set as implementation detail and introduce
FunctionTemplateDecl::findSpecialization.
Redeclarations of specializations will not cause the previous decl to be removed from the set,
the set will keep the canonical decl. findSpecialization will return the most recent redeclaration.
