This commit reverts a small portion of the switch to ThinLTO by default which changed the meaning of `-C lto` from "put the whole crate graph into one codegen unit" to "perform ThinLTO over the whole crate graph". This backport has no corresponding commit on master as rust-lang#47521 is making the same change but in a slightly different manner. This commit is intended to be a surgical change with low impact on beta. Closes rust-lang#47409

Does this PR need a higher bors priority because it is a beta-backport? |
