[PATCH] D124524: [demangler] Avoid nullptr UB

[Nathan Sidwell via Phabricator via llvm-commits]

urnathan added a comment.

alternatively could punt on the whole nullptr thing and just special case the zero-length memcpy and test comparison.  thoughts?
(For amusement value, I do know MIPS' memcpy routines segfault on `memcpy (dst, nullptr, 0)`)
