This patch replaces those occurrences of NoneType that would trigger
an error if the definition of NoneType were missing in None.h.

To keep this patch focused, I am deliberately not replacing None with
std::nullopt in this patch or updating comments.  They will be
addressed in subsequent patches.

This is part of an effort to migrate from llvm::Optional to
std::optional:
