This file pokes at the swift_reflection_projectExistential API
of the SwiftRemoteMirror library.
It tests the three conditions of existential layout:
- Class existentials
- Existentials whose contained type fits in the 3-word buffer
- Existentials whose contained type has to be allocated into a
raw heap buffer.
- Error existentials, a.k.a. `Error`.
