Auto merge of #70156 - michaelwoerister:incr-cgus, r=nikomatsakis
Make the rustc respect the `-C codegen-units` flag in incremental mode. This PR implements (the as of yet unapproved) major change proposal at https://github.com/rust-lang/compiler-team/issues/245. See the description there for background and rationale. The changes are pretty straightforward and should be easy to rebase if the proposal gets accepted at some point. r? @nikomatsakis cc @pnkfelix
