Improve plpgsql's handling of record field references by forcing all potential
field references in SQL expressions to have RECFIELD datum-array entries at
parse time. If it turns out that the reference is actually to a SQL column,
the RECFIELD entry is useless, but it costs little. This allows us to get rid
of the previous use of FieldSelect applied to a whole-row Param for the record
variable; which was not only slower than a direct RECFIELD reference, but
failed for references to system columns of a trigger's NEW or OLD record.
Per report and fix suggestion from Dean Rasheed.
