According to [dcl.inline]p7/note4,

And the declarations in the header unit are attached to the global
module fragment. So the function defined within a class definition in
header units should be implicitly inline too.
This fixes https://github.com/llvm/llvm-project/issues/57571.
If CLANG_LINK_CLANG_DYLIB, clang_target_link_libraries ignores all
indivial libraries and only links clang-cpp. As LLVMTestingSupport
is separate, pass it via target_link_libraries directly.
Clang has support of virtual file system for the purpose of testing, but
treatment of config files did not use it. This change enables VFS in it
as well.

LLVM contains a helpful function for getting the size of a C-style
array: `llvm::array_lengthof`. This is useful prior to C++17, but not as
helpful for C++17 or later: `std::size` already has support for C-style
arrays.
Change call sites to use `std::size` instead. Leave the few call sites that
use a locally defined `array_lengthof` that are meant to test previous bugs
with NTTPs in clang analyzer and SemaTemplate.

Previously, the heuristic was simply to look for template argument-
specific keywords, such as typename, class, template and auto
that are preceded by a left angle bracket <.
This changes the heuristic to instead look for a left angle bracket <
preceded by a right square bracket ], since according to the C++
grammar, the template arguments must *directly* follow the introducer.
(This sort of check might just end up being *too* aggressive)
This patch also adds a bunch more token annotator tests for lambdas,
specifically for some of the stranger forms of lambdas now allowed as
of C++20 or soon-to-be-allowed as part of C++23.

With the AlwaysBreakTemplateDeclarations option, having a constructor
template for a type consisting of all-uppercase letters with a
noexcept specifier would put said noexcept specifier on its own blank
line.
This is because the all-uppercase type is understood as a macro-like
attribute (such as DEPRECATED()), and noexcept is seen as the
declaration. However, noexcept is a keyword and cannot be an
identifier on its own.

- Add `AnalysisInputs` struct as the parameters for `checkDataflow`, and renamed `AnalysisData` struct to `AnalysisOutputs` which contains the data structures generated from a dataflow analysis run.
- Remove compulsory binding from statement to annotations. Instead, `checkDataflow` in the most general form takes a `VerifyResults` callback which takes as input an `AnalysisOutputs` struct. This struct contains the data structures generated by the analysis that can then be tested. We then introduce two overloads/wrappers of `checkDataflow` for different mechanisms of testing - one which exposes annotation line numbers and is not restricted to statements, and the other which exposes states computed after annotated statements. In the future, we should look at retrieving the analysis states for constructs other than statements.

`MatchSwitch` currently takes in matchers and functions for the `Stmt` class.
This patch generalises the match switch utility (renamed to `ASTMatchSwitch`) to work for different AST node types by introducing a template argument which is the base type for the AST nodes that the match switch will handle.
A `CFGMatchSwitch` is introduced as a wrapper around multiple `ASTMatchSwitch`s for different base types. It works by unwrapping `CFGElement`s into their contained AST nodes and passing the nodes to the relevant `ASTMatchSwitch`. The `CFGMatchSwitch` currently only handles `CFGStmt` and `CFGInitializer`.

By using a transfer function (`void transfer(const CFGElement *, ...)`) that takes a `CFGElement` as input, this patch extends user-defined analysis to all kinds of `CFGElement`. For example, users can now handle `CFGInitializer`s where `CXXCtorInitializer` AST nodes are contained.
