Original change's description:
> [maglev] Avoid emitting phis for exception context
>
> When the handler context register has a known value, we can avoid
> emitting a Phi for the value, by using the same merge logic on the
> handler-specific context register as we do for other registers. In
> practice, this means that the current context is always statically
> known, except when there is a generator.
