Aleksey Kladov 92da7e9ffa internal: optimize compile time
cargo llvm-lines shows that path_to_error bloats the code. I don't think
I've needed this functionality recently, seems that we've fixed most of
the serialization problems. So let's just remove it. Should be easy to
add back if we ever need it, and it does make sense to keep the
`from_json` function around.

//! 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.
