What Eli said :)

This can probably be fixed by setting NullIsUnknownSize <http://llvm.org/doxygen/structllvm_1_1ObjectSizeOpts.html> appropriately in callers of `llvm::getObjectSize`.

(We'll likely also want to ensure that the objectsize sanitizer in clang sets the nullunknown bit when it lowers to calls of `@llvm.objectsize` if clang's been handed this flag, but that's a different patch)
