Thanks @chhagedorn for the suggestion. The preconditions read better after renaming. Going over IR tests and removing @requires fields sounds good in order to run tests on all platforms and to consolidate tests.

Appreciate the review @robcasloz. I rewrote parts of the documentation and added more tests. Since we are implementing functionality that is similar to jtreg `@requires` reusing that implementation could be favorable.

This PR might be ready for another round of reviews.
