[PATCH] D64537: [WebAssembly] Implement thread-local storage (local-exec model)

[Guanzhong Chen via Phabricator via cfe-commits]

quantum updated this revision to Diff 209535.
quantum added a comment.

Guard `__wasm_init_tls` and TLS globals behind a flag (currently `--shared-memory`).

@tlively and I discussed offline and agreed that it's probably best to use the existing flag instead of adding another flag that needs to be passed when linking multi-threaded executables.
