The lower case spellings are C and C++ standard and are used in most
parts of the PostgreSQL sources. The upper case spellings are only used
in some files/modules. So standardize on the standard spellings.
The APIs for ICU, Perl, and Windows define their own TRUE and FALSE, so
those are left as is when using those APIs.
In code comments, we use the lower-case spelling for the C concepts and
keep the upper-case spelling for the SQL concepts.

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now superseded by the amvalidate checks.
