Subject: [PATCH 1/3] Simplify 'gcc/diagnostic-spec.h:nowarn_map' setup
If we've just read something from the map, we can be sure that it exists.
gcc/
* warning-control.cc (copy_warning): Remove 'nowarn_map' setup.
OK

Subject: [PATCH 2/3] Clarify 'key_type_t' to 'location_t' as used for
'gcc/diagnostic-spec.h:nowarn_map'
To make it obvious what exactly the key type is. No change in behavior.
gcc/
* diagnostic-spec.h (typedef xint_hash_t): Use 'location_t' instead
of...
(typedef key_type_t): ... this. Remove.
(nowarn_map): Document.
* diagnostic-spec.c (nowarn_map): Likewise.
* warning-control.cc (convert_to_key): Evolve functions into...
(get_location): ... these. Adjust all users.
OK
