Thomas Munro 6ae57f190e Fix exception safety bug in typcache.c. 
If an out-of-memory error was thrown at an unfortunate time,
ensure_record_cache_typmod_slot_exists() could leak memory and leave
behind a global state that produced an infinite loop on the next call.

Fix by merging RecordCacheArray and RecordIdentifierArray into a single
array.  With only one allocation or re-allocation, there is no
intermediate state.

Back-patch to all supported releases.
