Improve index AMs' opclass validation procedures.

Browse Source 
The amvalidate functions added in commit 65c5fcd353 were on the
crude side.  Improve them in a few ways:

* Perform signature checking for operators and support functions.

* Apply more thorough checks for missing operators and functions,
where possible.

* Instead of reporting problems as ERRORs, report most problems as INFO
messages and make the amvalidate function return FALSE.  This allows
more than one problem to be discovered per run.

* Report object names rather than OIDs, and work a bit harder on making
the messages understandable.

Also, remove a few more opr_sanity regression test queries that are
now superseded by the amvalidate checks.
