AtomicCell is used by neither non-parallel, nor parallel rustc, so I think it is fine to remove it. Removing all the unused methods from the non-parallel versions is a bad idea I think as the parallel do still have them. I think the non-parallel and parallel versions of all types should have an identical api surface to prevent confusion.

Hmm, not sure who a good reviewer would be - maybe r? @wesleywiser ?

There's a comment here that should be adjusted since we're removing AtomicCell

rust/compiler/rustc_data_structures/src/sync.rs

Line 87 in 35bab92

/// It differs from `AtomicCell` in that it has explicit ordering arguments

r=me after that.

It's confusing for these to be different, even if some of the methods
are unused.
