SharedArrayBuffer was disabled in https://bugs.webkit.org/show_bug.cgi?id=181266 due to Spectre and Meltdown vulnarabilities.

I haven't found tracking bug for re-enabling SAB again, so I created this one.

Chrome re-enabled SAB in v67 https://bugs.chromium.org/p/chromium/issues/detail?id=821270
Firefox re-enabled SAB in v78 https://bugzilla.mozilla.org/show_bug.cgi?id=1606624

As someone building a game, I would love to see Safari/WebKit re-enable SharedArrayBuffer. Sharing data between web workers and the main thread without SharedArrayBuffer is much slower, even though Safari is faster at a lot of things than other browsers.
