This patch mechanically replaces None with std::nullopt where the
compiler would warn if None were deprecated. The intent is to reduce
the amount of manual work required in migrating from Optional to
std::optional.
This is part of an effort to migrate from llvm::Optional to
std::optional:

A source location specifier class that holds a Declaration object containing
a FileSpec with line and column information. The column line is optional.
It also holds search flags that can be fetched by resolvers to look inlined
declarations and/or exact matches.
It describes a specific location in a source file and allows the user
to perform checks and comparaisons between multiple instances of that class.
