It's weird to have the core regression tests depending on contrib code, and coverage testing shows that those test queries add nothing to the core-code coverage of the core tests. So pull those test bits out and put them into ordinary test scripts inside contrib/spi/, making that more like other contrib modules. Aside from being structurally nicer, anything we can take out of the core tests (which are executed multiple times per check-world run) and put into tests executed only once should be a win. It doesn't look like this change will buy a whole lot of milliseconds, but a cycle saved is a cycle earned. Also, there is some discussion around possibly removing refint and/or autoinc altogether. I don't know if that will happen, but we'd certainly need to decouple them from the core tests to do so. The tests for autoinc were quite intertwined with the undocumented "ttdummy" trigger in regress.c. That made the tests very hard to understand and contributed nothing to autoinc's testing either. So I just deleted ttdummy and rewrote the autoinc tests without it. I realized while doing this that the description of autoinc in the SGML docs is not a great description of what the function actually does, so the patch includes some updates to those docs.
