Unrolled build for rust-lang#117615

Rollup merge of rust-lang#117615 - bjorn3:misc_changes, r=davidtwco Couple of small changes These are unrelated to each other, but they are each small enough that opening separate PR's doesn't make sense to me either. * Remove a place where the parse driver query is stolen. * Update an outdated doc comment * Use correct crate name in `-Zprint-vtable-sizes` when using `#![crate_name = "..."]`.
