Since igt_skip has funny control flow we can abuse it and make it work like a special kind of assert which automatically skips tests if a requirement fails. Note that in places where we have a less strict test which should always succeed (e.g. ioctl works or isn't available) the igt_assert should be place before the igt_require with the more strict requirements. Otherwise we'll skip a test instead of properly failing it. Convert a few users of igt_skip over to igt_require to showcase its use. v2: s/gem_check_/gem_require_/ so that we consistently use "require" to indicate magic check that can call igt_skip. Imo hiding the igt_require for feature checks is ok, but for more traditional assert like use cases an explicit igt_require might be better. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
