[PATCH] D99310: [deref] Handle byval/byref/sret/inalloc/preallocated arguments for deref-at-point semantics

Comment at: llvm/lib/IR/Value.cpp:747
+      if (ArgMemTy->isSized())
+        return false;

----------------
Why is the check for a sized type necessary? For an unsized type there would be no dereferenceable bytes, but I don't think it's something that really affects canBeFreed itself?
