fn early_bound_lifetimes_from_generics<'a, 'tcx: 'a>(

Expand description
Returns the early-bound lifetimes declared in this generics
listing. For anything other than fns/methods, this is just all
the lifetimes that are declared. For fns or methods, we have to
screen out those that do not appear in any where-clauses etc using
resolve_lifetime::early_bound_lifetimes
.
