Allan Shortlidge d438bac68d AST: Fix EnumDecl's hasPotentiallyUnavailableCaseValue() cache. ...

The cached values for `hasOnlyCasesWithoutAssociatedValues()` and
`hasPotentiallyUnavailableCaseValue()` are computed in a single pass over the
elements of an `EnumDecl`. However, the pass would return early after finding
an element with an associated value, without checking whether any of the rest
of the elements were potentially unavailable. This made `Comparable` synthesis
succeed for any enum with potentially unavailable elements so long as the first
element in the enum has an associated value.
