Update and cleanup HiPE records

The bulk of the changes concerns cleanups and code refactorings concerning
record constructions that assigned 'undefined' to record fields whose type
did not contain this value. See commit 8ce35b2.

While at it, some new type definitions were introduced and type names were
used instead of record type notation.  Minor code cleaups were also done.
