[clang][ASTImporter] Import source location of explicit object parameter instead of copying it (#124305)

We used to copy the `SourceLocation` instead of importing it, which
isn't correct since the `SourceManager`'s of the source and target
ASTContext might differ.

Also adds test that confirms that we import the explicit object
parameter location for `ParmVarDecl`s. This is how Clang determines
whether a parameter `isExplicitObjectParamater`. The LLDB expression
evaluator relies on this for calling "explicit object member functions".

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.
