This patch replaces uses of StringRef::{starts,ends}with with
StringRef::{starts,ends}_with for consistency with
std::{string,string_view}::{starts,ends}_with in C++20.
I'm planning to deprecate and eventually remove
StringRef::{starts,ends}with.
This upstreams a part of the C++ namespaces support in Clang API Notes.
The complete patch was recently merged downstream in the Apple fork: https://github.com/apple/llvm-project/pull/7230.
This patch only adds the parts of the namespace support that can be cleanly applied on top of the API Notes infrastructure that was upstreamed previously.

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 adds the skeleton of the YAML Compiler for APINotes. This change
only adds the YAML IO model for the API Notes along with a new testing
tool `apinotes-test` which can be used to verify that can round trip the
YAML content properly. It provides the basis for the future work which
will add a binary serialization and deserialization format to the data
model.
This is based on the code contributed by Apple at
https://github.com/llvm/llvm-project-staging/tree/staging/swift/apinotes.
