Merge #4489
4489: Memory allocation optimization r=matklad a=simonvandel I did some profiling using DHAT, and this was what I could easily optimize without much knowledge of the codebase. This speeds up analysis-stats on rust-analyser by ~4% on my local machine. **Benchmark** ➜ rust-analyzer-base git:(master) hyperfine --min-runs=2 '/home/simon/Documents/rust-analyzer/target/release/rust-analyzer analysis-stats .'
