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.

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.

Random pipeline closure is less likely to kill pending pipelines.
<!-- Please describe your changes on the following line: -->
Make it less likely for pending pipelines to be randomly killed. Pending pipelines send more messages to the constellation, so at the moment we're skewing to killing pipelines early in their lifetimes.
