Browse Source 
use `#[align]` attribute for `fn_align`

Tracking issue: https://github.com/rust-lang/rust/issues/82232

https://github.com/rust-lang/rfcs/pull/3806 decides to add the `#[align]` attribute for alignment of various items. Right now it's used for functions with `fn_align`, in the future it will get more uses (statics, struct fields, etc.)

(the RFC finishes FCP today)
