Sam Clegg 29a3056bb5 [lld][WebAssembly] Allow references to __tls_base without shared memory 
Previously we limited the use of atomics and TLS to programs
linked with `--shared-memory`.

However, as of https://reviews.llvm.org/D79530 we now allow
programs that use atomic to be linked without `--shared-memory`.
For this to be useful we also want to all TLS usage in such
programs.  In this case, since we know we are single threaded
we simply include the TLS data as a regular active segment
and create an immutable `__tls_base` global that point to the
start of this segment.
