ICE building warp with 1.39.0-beta.2

[tomjakubowski]

I was unsure whether to file here or on the rust project itself, but an ordinary cargo build doesn't fail so I'm trying here first.

Building the warp crate as a dependency with RLS 1.39.0-beta.2 reliably causes an ICE on my machine.

Sample crate:
rls-warp-ice.tar.gz

To reproduce the error, run rustup add beta, and then cd to the project directory and run rls +beta --cli.

Log:
