// If AST loaded module verification is run after type checking the empty source
// file (rdar36801676_empty.swift), but before type checking this source file,
// then the importer caches the declaration for PasteboardType's constructor
// without synthesizing it's body. Eventually, the SILVerifier will raise a linkage error:
// SIL verification failed: external declarations of SILFunctions with shared
// visibility is not allowed: SingleFunction ||
// !hasSharedVisibility(RefF->getLinkage()) || RefF->hasForeignBody()
