Rollup merge of #104797 - weihanglo:stream-write-dwp, r=jackh726
rustc_codegen_ssa: write `.dwp` in a streaming fashion When writing a `.dwp` file, rustc writes to a Vec first then to a BufWriter-wrapped file. It seems very likely that we can write in a streaming fashion to avoid double buffering in an intermediate Vec. On my Linux machine, `.dwp` from the latest rust-lang/cargo is 113MiB. It may worth a stream writer, though I didn't do any benchmark 🙇🏾♂️.
