A recent change taught TBD generation to skip @_silgen_name variables that have no initial value, since such a global is just a forward declaration of a symbol defined elsewhere. But computed properties never have an initial value either, so a @_silgen_name computed property, like the ones libraries keep around to preserve old ABI, lost its accessors and property descriptor from the TBD even though IRGen still emits them, and TAPI then rejects the build. Only treat global storage that way, which matches how SILGen decides a @_silgen_name variable is a declaration rather than a definition.
