Anonymous 602190f66f LibJS: Fix mixing of logical and coalescing operators ...

The same expression is not allowed to contain both the
logical && and || operators, and the coalescing ?? operator.

This patch changes how "forbidden" tokens are handled, using a
finite set instead of an Vector. This supports much more efficient
merging of the forbidden tokens when propagating forward, and
allowing the return of forbidden tokens to parent contexts.
