Robert Widmann 9e4670a605 Implement Casting For Extended Existentials ...

Implement casting to and from extended existentials. This is done by slightly generalizing the conditional conformances checking infrastructure.

Unfortunately, casts for reference types and metatypes are unsound because IRGen is peepholing all non-opaque existential conversions with a helper. I’ll disable that in a follow-up.
