[Ada] Deconstruct deferred references
While cleaning up and modifying code for unreferenced warnings we
removed all calls to Defer_Reference, which was the only routine that
populated the Deferred_References table. Consequently, all the code
related to this table became dead.
gcc/ada/
* lib-xref.ads (Deferred_Reference_Entry, Defer_Reference,
Process_Deferred_References, Has_Deferred_Reference): Remove
client API.
* lib-xref.adb (Deferred_References, Defer_Reference,
Has_Deferred_Reference, Process_Deferred_References): Remove
implementation.
* frontend.adb, sem_ch11.adb, sem_ch5.adb, sem_res.adb,
sem_util.adb, sem_warn.adb: Remove uses of Deferred_References.
