Make more of the test suite run on Mac Catalyst This adds the `only-apple`/`ignore-apple` compiletest directive, and uses that basically everywhere instead of `only-macos`/`ignore-macos`. Some of the updates in `run-make` are a bit redundant, as they use `ignore-cross-compile` and won't run on iOS - but using Apple in these is still more correct, so I've made that change anyhow. 2024-05-27 15:17:18 +02:00			`//@ ignore-apple: cycle error does not appear on apple`

Detect cycles and specialize error reporting for Sized. It is important to get the `Sized` error usable, since that hits new users frequently. Further work is needed for the error reporting for non-Sized cycle cases; those currently just fallback to the old path. Also adjust tests. 2016-01-08 21:41:37 -05:00			//~^ ERROR recursive type `Foo` has infinite size
