This is needed for Atomic::from_mut.

This reverts commit 5ef1db3.

Instead of a few hardcoded cfg(target_arch = ..) like before.

This was missed in PR rust-lang#75465. As a result, a few places have been using
the full body span of functions, instead of just the header span.

I little clarification

Continuation of rust-lang#74526

Adds the #[track_caller] attribute to almost all panicking Cell
functions. The ones that borrow two Cells in their function
body are spared, because the panic location helps pinpoint
which of the two borrows failed. You'd need to have
full debuginfo and backtraces enabled together with column
info in order to be able to discern the cases.
Column info is only available on non-Windows platforms.

Record `tcx.def_span` instead of `item.span` in crate metadata

emit errors during AbstractConst building

There changes are currently still untested, so I don't expect this to pass CI 😆

It seems to me like this is the direction we want to go in, though we didn't have too much of a discussion about this.

…-from-mut, r=Amanieu

Add cfg(target_has_atomic_equal_alignment) and use it for Atomic::from_mut.

Fixes some platform-specific problems with rust-lang#74532 by using the actual alignment of the types instead of hardcoding a few `target_arch`s.

Changing the alloc() to accept &self instead of &mut self

Fixes: [rust-lang#55](rust-lang/wg-allocators#55)

This is the first cut. It only makes the change for `alloc` method.

fix small typo in docs and comments

Fixed `the the` to `the`, as far as I found.

Add #[track_caller] to more panicking Cell functions

Continuation of rust-lang#74526

Adds the #[track_caller] attribute to almost all panicking Cell
functions. The ones that borrow two Cells in their function
body are spared, because the panic location helps pinpoint
which of the two borrows failed. You'd need to have
full debuginfo and backtraces enabled together with column
info in order to be able to discern the cases.
Column info in debuginfo is only available on non-Windows platforms.
