[clang] Use StringRef::{starts,ends}_with (NFC) (#75149)
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.

b0abd4893f [llvm] Add missing StringExtras.h includes
In preparation for removing the `#include "llvm/ADT/StringExtras.h"`
from the header to source file of `llvm/Support/Error.h`, first add in
all the missing includes that were previously included transitively
through this header.

6ad0788c33 [clang] Use std::optional instead of llvm::Optional (NFC)
This patch replaces (llvm::|)Optional< with std::optional<.  I'll post
a separate patch to remove #include "llvm/ADT/Optional.h".

This is part of an effort to migrate from llvm::Optional to
std::optional:

a1580d7b59 [clang] Add #include <optional> (NFC)
This patch adds #include <optional> to those files containing
llvm::Optional<...> or Optional<...>.

I'll post a separate patch to actually replace llvm::Optional with
std::optional.

This is part of an effort to migrate from llvm::Optional to
std::optional:

53e5cd4d3e llvm::Optional::value => operator*/operator->
std::optional::value() has undesired exception checking semantics and is
unavailable in older Xcode (see _LIBCPP_AVAILABILITY_BAD_OPTIONAL_ACCESS). The
call sites block std::optional migration.

This makes `ninja clang` work in the absence of llvm::Optional::value.

7b6fe711b2 Refactor StaticAnalyzer to use clang::SarifDocumentWriter
Refactor StaticAnalyzer to use clang::SarifDocumentWriter for
serializing sarif diagnostics.

Uses clang::SarifDocumentWriter to generate SARIF output in the
StaticAnalyzer.

Various bugfixes are also made to clang::SarifDocumentWriter.

Summary of changes:

clang/lib/Basic/Sarif.cpp:
  * Fix bug in adjustColumnPos introduced from prev move, it now uses
    FullSourceLoc::getDecomposedExpansionLoc which provides the correct
    location (in the presence of macros) instead of
    FullSourceLoc::getDecomposedLoc.
  * Fix createTextRegion so that it handles caret ranges correctly,
    this should bring it to parity with the previous implementation.

clang/test/Analysis/diagnostics/Inputs/expected-sarif:
  * Update the schema URL to the offical website
  * Add the emitted defaultConfiguration sections to all rules
  * Annotate results with the "level" property

clang/lib/StaticAnalyzer/Core/SarifDiagnostics.cpp:
  * Update SarifDiagnostics class to hold a clang::SarifDocumentWriter
    that it uses to convert diagnostics to SARIF.

1bd2b2dce2 Add support for specifying the severity of a SARIF Result
* Extend SarifResult with level property, and allow rule configuration
* Create SarifReportingConfiguration which allow configuring rules with
a default priority, severity and an enable-toggle
* Support for setting the level property[1] of a result.

If unset, it defaults to "warning", which is the result of an empty
default configuration on rules[2]

4b03ad6506 [clang] Emit SARIF Diagnostics: Create clang::SarifDocumentWriter interface
[clang] Emit SARIF Diagnostics: Create clang::SarifDocumentWriter interface

Create an interface for writing SARIF documents from within clang:

The primary intent of this change is to introduce the interface
clang::SarifDocumentWriter, which allows incrementally adding
diagnostic data to a JSON backed document. The proposed interface is
not yet connected to the compiler internals, which will be covered in
future work. As such this change will not change the input/output
interface of clang.

This change also introduces the clang::FullSourceRange type that is
modeled after clang::SourceRange + clang::FullSourceLoc, this is useful
for packaging a pair of clang::SourceLocation objects with their
corresponding SourceManagers.
