Remove obsolete RECHECK keyword completely

Browse Source 
This used to be part of CREATE OPERATOR CLASS and ALTER OPERATOR
FAMILY, but it has done nothing (except issue a NOTICE) since
PostgreSQL 8.4.  Commit 30e7c175b8 removed support for dumping from
pre-9.2 servers, so this no longer serves any need.

This now removes it completely, and you'd get a normal parse error if
you used it.
