Rollup merge of rust-lang#142410 - RalfJung:align_of, r=WaffleLapkin,workingjubilee

matthiaskrgr · web-flow · commit 86e9995e7ab8 · 2025-06-13T05:16:59.000+02:00
intrinsics: rename min_align_of to align_of Now that `pref_align_of` is gone (rust-lang#141803), we can give the intrinsic backing `align_of` its proper name. r? `@workingjubilee` or `@bjorn3`
