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:

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.

Rename methods to clearly signal when they only deal with ASCII,
simplify the parsing of identifier, and use start/continue instead of
head/body for consistency with Unicode terminology.
Adds the `between` combinator and registers it with the parser. As a driveby, updates some deprecated names to their current versions.

This patch adds a parser for a `RangeSelector` written as a string. The format
is closely based on the way one would right the selector in C++. This should
enable use of `RangeSelector`s from tools like clang-query and web UIs.
