Fix or update tests for remaining php 8.0 failures on nightly builds

[TysonAndre]

e.g. add a different test if the rendering of cyclic values is slightly different in php 8.0

[heddn]

Is this what is causing my compile failures in https://git.mtech-llc.com/open-source/drupal-docker/-/jobs/5770#L708

@heddn it looks separate API change

[TysonAndre]

That looks like an issue in phpredis at a glance. Also, I haven't checked, but you want the master branch of igbinary - the php8 compatibility fixes for the latest commits to php 8.0 aren't in a pecl release yet.

Same for php redis - it needs to use master phpredis/phpredis@a7662da

[heddn]

I'm using the develop branch now for redis. I'll see about doing the same for igbinary as well. Thanks.

[TysonAndre]

It seems like the issue @heddn reported was (potentially) fixed in phpredis/phpredis@a7662da

[TysonAndre]

Check for reference serialization (Original example, not using var_dump) [tests/igbinary_009b.phpt]
Cyclic array test [tests/igbinary_026.phpt]
Cyclic array test 2 [tests/igbinary_026b.phpt]

These all seem harmless, and the only thing that changed was the var_dump output for cyclic reference arrays after unserialization (and possibly before, unrelated to igbinary)

Yes, this tests probably needs split for 8.x

Yes, this tests probably needs split for 8.x

I was planning on that if that was only a change in the representation emitted by var_dump (or handling of cyclic arrays when passed to functions by php)
