Dan Gohman 59726668f1 [WebAssembly] Strip TLS when "atomics" is not enabled ...

With f3b4f99007, the exclusive source of
truth for whether threads are supported is the -matomics flag.
Accordingly, strip TLS flags when -matomic is not specified, even if
bulk-memory is specified and it would theoretically be supportable.
This allows the backend to compile TLS variables when -mbulk-memory is
enabled but threads are not enabled.
