Mark atomics as unsupported on thumbv6m
The thumbv6m target does not support atomics. Historically, LLVM had a bug where atomic load/stores for this target were emitted as plain load/stores rather than as libatomic calls. This was fixed in https://reviews.llvm.org/D120026, which will be part of LLVM 15. As we require that "atomic support" does not use libatomic, we need to indicate that this target does not have native atomics.
