Casting `*const T` to `*const U` with `U: Sized` is allowed even if `T: ?Sized`.
This safely extracts the data pointer out of a trait object,
without relying on the memory representation of trait objects.
Make optional the usage of some unstable features
With `--no-default-features --features default-except-unstable`, more crates can now be compiled on stable Rust. This will help integrate them in rustc’s regression testing and compiler performance benchmarking.

style: Split the invalidation processing from the invalidator step.
This is the first step in reusing the invalidation machinery for other stuff,
potentially including QuerySelector / QuerySelectorAll.

Reduce the blur and spread radius size of a reftest.
In the near future, we'll be changing the blur algorithm in WR.
On native GPUs, this is fine - but on OSMesa, a blur of this
radius and spread is quite slow, and can cause test timeouts
when running with a lot of processes enabled.
Reducing the spread / blur shouldn't affect what this is testing.
