5e29333d6b [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.

(cherry picked from commit 3380331e7e)

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.
