Description
I'd like to have debug assertions enabled for local rustc builds, but if I didn't change rustc then I am okay with just downloading the prebuilt rustc even if it does not have debug assertions. I'll hopefully only have to debug rustc if I actually changed it. :)
Would be nice to have a way to force the download even if settings differ.

Research direction
Start by tracing bootstrap's handling of download-rustc=if-unchanged and how it compares build settings. Determine where an option could permit downloading the prebuilt rustc despite differing debug-assertion settings. Done means unchanged local rustc builds can use the download while existing settings behavior remains intact.
