Pass +atomics-32 feature for thumbv6m target
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.
