Make def names and HIR names consistent.
The name in the `DefKey` is interned to create the `DefId`, so it does not
require any query to access. This can be leveraged to avoid a few useless
HIR accesses for names.
~In order to achieve that, generic parameters created from universal
impl-trait are given the pretty-printed ast as a name, instead of
`{{opaque}}`.~
~Drive-by: the `TyCtxt::opt_item_name` used a dummy span for non-local
definitions. We have access to `def_ident_span`, so we use it.~
