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:
https://discourse.llvm.org/t/deprecating-llvm-optional-x-hasvalue-getvalue-getvalueor/63716
This patch adds a `buildAccess` function, which constructs a string with the
proper operator to use based on the expression's form and type. It also adds two
predicates related to smart pointers, which are needed by `buildAccess` but are
also of general value.
We deprecate `buildDot` and `buildArrow` in favor of the more general
`buildAccess`. These will be removed in a future patch.

This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.
This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.
This doesn't actually modify StringRef yet, I'll do that in a follow-up.
Summary:
The Transformer library has been growing inside of
lib/Tooling/Refactoring. However, it's not really related to anything else in
that directory. This revision moves all Transformer-related files into their own
include & lib directories. A followup revision will (temporarily) add
forwarding headers to help any users migrate their code to the new location.

idiomatic use of parentheses and the address-of, dereference and member-access
operators (dot and arrow) and queries about need for parentheses.
