      .Clang and LLVM now support `zstd` for debug section compression

      By default, Clang and LLVM tools use `Zlib` as the algorithm for debug section compression. With this enhancement, users can alternatively use the Zstandard (`zstd`) algorithm which can reach a higher compression rate than `Zlib`.

      For example, if you want to use `zstd` compression when you compile a program with Clang, use the following command:

      ----
      $ clang -Wa,-compress-debug-sections=zstd -Wl,--compress-debug-sections=zstd ...
      ----
