Lower atomic operations to their regular non-atomic equivalents. Lowering for all operations except atomic fence is done at DAG legalization time. Fences are removed at instruction emission time.

Lower atomic operations to their regular non-atomic equivalents. Lowering for all operations except atomic fence is done at DAG legalization time. Fences are removed at instruction emission time. The custom lowering is done only for the SBF subtarget, BPF atomics still work (and tests still pass).
This will allow us to remove all the atomic stubs we have behind
#[cfg(target_arch = "sbf")]in rustc, and implements some things we hadn't stubbed yet, making all atomics test pass.
