[clang-repl] Lay the basic infrastructure for pretty printing of types (#148701)

The idea is to store a type-value pair in clang::Value which is updated
by the interpreter runtime. The class copies builtin types and boxes
non-builtin types to provide some lifetime control.

The patch enables default printers for C and C++ using a very
minimalistic approach. We handle enums, arrays and user types. Once we
land this we can focus on enabling user-defined pretty-printers which
take control over printing of types

The work started as part of https://reviews.llvm.org/D146809, then we
created a giant in https://github.com/llvm/llvm-project/pull/84769

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.
