Since this was brought up in today's compiler team meeting, I'm assuming there's no need to also cc compiler-team/contributors to make them aware of this change. @bors r+ |

I've tried not to change anything that looked similar to
rustc --print, where people might use automation, and/or any "bulk" prints, such as dumping an entire Graphviz (dot) graph on stdout.The reason I want
-Ztime-passesto be on stderr like debug logging is I can get a complete (and correctly interleaved) view just by looking at stderr, which is merely a convenience when runningrustc/Cargo directly, but even more important when it's nested in a build script, as Cargo will split the build script output into stdout (namedoutput) andstderr.
