CI: make downgrade and slow integration tests depend on check-compiled-source step.

As pointed out by Alex Myers: we don't want to waste time running the
complex steps if the generated files are not up-to-date.

But we still run the faster "integration" tests (not valgrind or
sanitizer ones), since they often reveal early failures.
