Aleksey Kladov 797185e1b6 internal: switch from CLI to internal benchmarking
We have a CLI for benchmarking, but no one actually uses it it seems.
Let's try switching to "internal" benchmarks, implemented as rust tests.
They should be easier to "script" to automate tracking of perf
regressions.

//! Implementation of the LSP for rust-analyzer.
//!
//! This crate takes Rust-specific analysis results from ide and translates
//! into LSP types.
//!
//! It also is the root of all state. `world` module defines the bulk of the
//! state, and `main_loop` module defines the rules for modifying it.
//!
//! The `cli` submodule implements some batch-processing analysis, primarily as
//! a debugging aid.
