3380331e7e [SE-0470] Enable isolated conformances by default 
The IsolatedConformances feature moves to a normal, supported feature.
Remove all of the experimental-feature flags on test cases and such.

The InferIsolatedConformances feature moves to an upcoming feature for
Swift 7. This should become an adoptable feature, adding "nonisolated"
where needed.

35097b5a71 Optimizer: simplify unconditional_checked_cast to existential metatypes. 
Replace `unconditional_checked_cast` to an existential metatype with an `init_existential_metatype`, it the source is a conforming type.
Note that init_existential_metatype is better than unconditional_checked_cast because it does not need to do any runtime casting.
