Auto merge of #38072 - nikomatsakis:bootstrap-incremental, r=acrichto
add preliminary support for incremental compilation to rustbuild.py This implements the integration described in #37929. It requires the use of a local nightly as your bootstrap compiler. The setup is described in `src/bootstrap/README.md`. This does NOT implement the "copy stage0 libs to stage1" optimization described in #37929, just because that seems orthogonal to me. In local testing, I do not yet see any incremental re-use when building rustc. I'm not sure why that is, more investigation needed. (For these reasons, this is not marked as fixing the relevant issue.) r? @alexcrichton -- I included one random cleanup (`Step::noop()`) that turned out to not be especially relevant. Feel free to tell me you liked it better the old way.
