When constructing a SILDeclRef for a bare DestructorDecl, prefer the Deallocator.
When constructing a SILDeclRef for a bare DestructorDecl, prefer the Deallocator.

This mimics what we do for ConstructorDecls, and all of the callers
already DTRT here. Fixes the first half of <rdar://problem/15883734>.
