Andrew Trick 762cdc4c94 Fix PredictableDeadAllocationElimination ownership for empty structs ...

Preserve ownership for empty non-trivial structs. This currently applies to
~Escapable structs. People often use empty structs to investigate language
behavior. They should behave just like a struct that wraps a
pointer.

Previously, this would crash later during OSSA lifetime completion:

Assertion failed: (isa<UnreachableInst>(block->getTerminator())),
function computeRegion, file OSSALifetimeCompletion.cpp.
