[alpha.webkit.RetainPtrCtorAdoptChecker] Support adopt(cast(copy(~)) (#132316)

This PR adds the support for recognizing calling adoptCF/adoptNS on the
result of a cast operation on the return value of a function which
creates NS or CF types. It also fixes a bug that we weren't reporting
memory leaks when CF types are created without ever calling RetainPtr's
constructor, adoptCF, or adoptNS.

To do this, this PR adds a new mechanism to report a memory leak
whenever create or copy CF functions are invoked unless this CallExpr
has already been visited while validating a call to adoptCF. Also added
an early exit when isOwned returns IsOwnedResult::Skip due to an
unresolved template argument.

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
