https://reviews.llvm.org/D120026 changed atomics on thumbv6m to use libatomic, to ensure that atomic load/store are compatible with atomic RMW/CAS. However, Rust wants to expose only load/store without libcalls. https://reviews.llvm.org/D130480 added support for this behind the +atomics-32 target feature, so enable that feature. |

The codegen crate contains the code to convert from MIR into LLVM IR,
and then from LLVM IR into machine code. In general it contains code
that runs towards the end of the compilation process.
For more information about how codegen works, see the rustc dev guide.
