Avoid double lowering of generic identifiers.

Browse source 
`lower_generic_bound_predicate` calls `lower_ident`, and then passes the
lowered ident into `new_named_lifetime`, which lowers it again. This
commit avoids the first lowering. This requires adding a `lower_ident`
call on a path that doesn't involve `new_named_lifetime`.
