Rollup merge of #131375 - klensy:clone_on_ref_ptr, r=cjgillot

compiler: apply clippy::clone_on_ref_ptr for CI

Apply lint https://rust-lang.github.io/rust-clippy/master/index.html#/clone_on_ref_ptr for compiler, also see https://github.com/rust-lang/rust/pull/131225#discussion_r1790109443.

Some Arc's can be misplaced with Lrc's, sorry.
