[NFC] As part of using inclusive language within the llvm project, this patch
rewords a comment to replace Whitelist with Allowlist in
`RetainSummaryManager.cpp`.

This is mostly a mechanical change, but a testcase that contains
parts of the StringRef class (clang/test/Analysis/llvm-conventions.cpp)
isn't touched.
It is a reference-counted class but it uses different methods for that
and the checker doesn't understand them yet.

There is no syntax like {@code ...} in Doxygen, @code is a block command
that ends with @endcode, and generally these are not enclosed in braces.
The correct syntax for inline code snippets is @c <code>.

This reverts commit 3500cc8d89.
This old commit was made over a completely false premise. OSSymbols
aren't different from other OSObjects and we shouldn't treat them
differently for the purposes of static analysis.
So far we've been dropping coverage every time we've encountered
a CXXInheritedCtorInitExpr. This patch attempts to add some
initial support for it.
Constructors for arguments of a CXXInheritedCtorInitExpr are still
not fully supported.

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.
It's a new API for custom RTTI in Apple IOKit/DriverKit framework that is
similar to OSDynamicCast() that's already supported, but crashes instead of
returning null (and therefore causing UB when the cast fails unexpectedly).
Kind of like cast_or_null<> as opposed to dyn_cast_or_null<> in LLVM's RTTI.
Historically, RetainCountChecker was responsible for modeling OSDynamicCast.
This is simply an extension of the same functionality.

In the OSObject universe there appears to be another slightly popular contract,
apart from "create" and "get", which is "matching". It optionally consumes
a "table" parameter and if a table is passed, it fills in the table and
returns it at +0; otherwise, it creates a new table, fills it in and
returns it at +1.
For now suppress false positives by doing a conservative escape on all functions
that end with "Matching", which is the naming convention that seems to be
followed by all such methods.

Don't crash when a function has a name that starts with "CF" and ends with
"Retain" but takes 0 arguments. In particular, don't try to treat it as if
it returns its first argument.
These problems are inevitable because the checker is naming-convention-based,
but at least we shouldn't crash.

Track them for ISL/OS objects by default, and for NS/CF under a flag.

ARCMigrator is using code from RetainCountChecker, which is a layering
violation (and it also does it badly, by using a different header, and
then relying on implementation being present in a header file).
This change splits up RetainSummaryManager into a separate library in
lib/Analysis, which can be used independently of a checker.
