Subject: repl: fix crash when SharedArrayBuffer disabled
It's possible for SharedArrayBuffers to be disabled with
--no-harmony-sharedarraybuffer so we first need to check that this
isn't the case before attempting to use them in the repl or a crash occurs.
Upstreamed at https://github.com/nodejs/node/pull/39718.
