[PATCH] D124524: [demangler] Avoid nullptr UB

[David Blaikie via Phabricator via llvm-commits]

Hmm - why does this need an allocation, though? A `StringPiece(nullptr, nullptr)` sounds valid to me? Is something using a distinction between StringPiece that's zero-length but non-null and StringPiece that's null?
