bors 329dde57fd Auto merge of #53524 - alexcrichton:buffer-out, r=eddyb 
Buffer LLVM's object output stream

In some profiling on OSX I saw the `write` syscall as quite high up on
the profiling graph, which is definitely not good! It looks like we're
setting the output stream of an object file as directly to a file
descriptor which means that we run the risk of doing lots of little
writes rather than a few large writes.

This commit fixes this issue by adding a buffered stream on the output,
causing the `write` syscall to disappear from the profiles on OSX.

This directory contains the source code of the rust project, including:

  • rustc and its tests
  • libstd
  • Various submodules for tools, like rustdoc, rls, etc.

For more information on how various parts of the compiler work, see the rustc guide.
