Don't warn about jumping into a construct if we're DIE-ing

There are many cases where we throw exceptions if you attempt to goto
somewhere you have no business going. We'd *also* throw a deprecation
warning in these cases, which just seems silly. Deprecated means "this
will stop working eventually", so there's no need to throw that when
we're just going to die right now.
