 support platforms without 64-bit atomic types
 As explained in https://doc.rust-lang.org/std/sync/atomic/#portability,
 some platforms don't have 64-bit atomic types.  As a result of
 `smallvec` being used by `pydantic-core`, this crate is involved in some
 dependency chains in Debian where we currently support the armel and
 powerpc architectures, neither of which have these types.
 .
 Since the `malloc_size_of_is_0!` macro just implements a trait on the
 types it's called with, it should be fine to skip types that don't exist
 on the target platform.
 .
 Bumps MSRV to 1.60 for `#[cfg(target_has_atomic = "...")]`.
