Simplified repro for bug.

Seeing a spurious "exception specification of overriding function is more lax
than base version" error when building with modules, apparently from clang not
being able to deduce that a base class destructor is noexcept from after
serializing (but not that sure here).  Repro is attached and also available at
https://reviews.llvm.org/differential/diff/161382/.
