[-Wunsafe-buffer-usage] Fixits for array args of func-ptr calls (#80358)

Currently we ignore calls on function pointers (unlike direct calls of
functions and class methods). This patch adds support for function pointers as
well.

The change is to simply replace use of forEachArgumentWithParam matcher in UPC
gadget with forEachArgumentWithParamType.

from the documentation of forEachArgumentWithParamType:
/// Matches all arguments and their respective types for a \c CallExpr or
/// \c CXXConstructExpr. It is very similar to \c forEachArgumentWithParam but
/// it works on calls through function pointers as well.

Currently the matcher also uses hasPointerType() which checks that the
canonical type of an argument is pointer and won't match on arrays decayed to
pointer. Replacing hasPointerType() with isAnyPointerType() which allows
implicit casts allows for the arrays to be matched as well and this way we get
fixits for array arguments to function pointer calls too.

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
