Add a test to pg_upgrade's test suite that verifies that dump-restore-dump of regression database produces equivalent output to dumping it directly. This was already being tested by running pg_upgrade itself, but non-binary-upgrade mode was not being covered. The regression database has accrued, over time, a sufficient collection of interesting objects to ensure good coverage, but there hasn't been a concerted effort to be completely exhaustive, so it is likely still possible to have more. This'd belong more naturally in the pg_dump test suite, but we chose to put it in src/bin/pg_upgrade/t/002_pg_upgrade.pl because we need a run of the regression tests which is already done here, so this has less total test runtime impact. Also, experiments have shown that using parallel dump/restore is slightly faster, so we use --format=directory -j2. This test has already reported pg_dump bugs, as fixed in fd41ba93e463, 74563f6b9021, d611f8b1587b, 4694aedf63bf.
