`rls` no longer builds after rust-lang/rust#61274

[rust-highfive]

Hello, this is your friendly neighborhood mergebot.
After merging PR #61274, I observed that the tool rls no longer builds.
A follow-up PR to the repository https://github.com/rust-lang/rls is needed to fix the fallout.

cc @Centril, do you think you would have time to do the follow-up work?
If so, that would be great!

cc @Centril, the PR reviewer, and @rust-lang/compiler -- nominating for prioritization.

I'm going to guess that #61164 is to blame; cc @RalfJung

The fix is mostly to replace Scalar::Bits { bits, size } by Scalar::Raw { data, size }.

But really RLS shouldn't be using such implementation details...

The logs look like the failure is in clippy, not RLS? I am confused.

(Great logs as usual, thanks Travis.)

@RalfJung breaking clippy breaks RLS, AFAIK.

rust-lang/rust-clippy#4152 will fix it, only needs ci to pass.
