[alpha.webkit.UncountedLocalVarsChecker] Allow uncounted object references within trivial statements (#82229)

This PR makes alpha.webkit.UncountedLocalVarsChecker ignore raw
references and pointers to a ref counted type which appears within
"trival" statements. To do this, this PR extends TrivialFunctionAnalysis
so that it can also analyze "triviality" of statements as well as that
of functions Each Visit* function is now augmented with
withCachedResult, which is responsible for looking up and updating the
cache for each Visit* functions.

As this PR dramatically improves the false positive rate of the checker,
it also deletes the code to ignore raw pointers and references within if
and for statements.

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices libc++

Welcome to the LLVM project!

This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.

The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.

C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.

Other components include: the libc++ C++ standard library, the LLD linker, and more.

Getting the Source Code and Building LLVM

Consult the Getting Started with LLVM page for information on building and running LLVM.

For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.

Getting in touch

Join the LLVM Discourse forums, Discord chat, LLVM Office Hours or Regular sync-ups.

The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
