Unrolled build for #142303

Rollup merge of #142303 - Kobzol:bootstrap-cleanup-1, r=jieyouxu

Assorted bootstrap cleanups (step 1)

Now that the stage0 redesign has landed, we can finally start cleaning up many things in bootstrap, and lord knows it deserves it! I plan to send many PRs once I figure out an incremental way forward, this is the first one of them. It doesn't actually change anything, just renames stuff and adds more documentation, but the rename is bitrotty, so I wanted to push the PR eagerly.
