Deletion logic was running at snapshot time, and snapshots don't have global.Atomics, so this just stopped deleting Atomics.wake. This is fixed by creating a new C++ helper that is called after both Context::New and Context::FromSnapshot.

node v12.5 - v12.10 all mistakenly have this method; i hope this is considered a patch, though, and not a major :-/

LGTM if @joyeecheung is good with this, although I’m surprised that snapshots don’t also include the state of builtins…

@addaleax any flagged features will not be included in snapshots, even if they're enabled by default, because they could be disabled at runtime by using V8::SetFlags.

In this case if (global.Atomics) {} was never running because global.Atomics was undefined.

It looks more reasonable to do this later than InitializeContext() here since logically InitializeContext is supposed to give you a context that looks like the one created with Context::FromSnapshot
