[ASTERIXDB-2516][COMP] Avoid writing field names & values when comparing records
- user model changes: no
- storage format changes: no
- interface changes: no
Details:
ARecordVisitablePointable writes field names, field tags, and field values
first before giving access to the record information. This is not ideal for
comparison. A different record accessor is needed for comparison. Also, the
field names should be sorted which ARecordVisitablePointable does not provide.
- avoid this writing when a pointable to the name & value can be obtained
(especially when the field value already includes the tag)
- use UTF8Pointable cached values (string length, meta length) to compare
instead of using the string comparator which would recalculate these values
- refactored some common code.
- removed not used methods in ARecordPointable
