[lldb] Implement TrackingOutputBuffer to track demangled name information (#131836)

This patch implements a new `TrackingOutputBuffer` which tracks where the scope/basename/arguments begin and end in the demangled string.

The idea that a function name can be decomposed into <scope, base, arguments>. The assumption is that given the ranges of those three elements and the demangled name, LLDB will be able to to reconstruct the full demangled name. The tracking of those ranges is pretty simple. We don’t ever deal with nesting, so whenever we recurse into a template argument list or another function type, we just stop tracking any positions. Once we recursed out of those, and are back to printing the top-level function name, we continue tracking the positions.

We introduce a new structure `FunctionNameInfo` that holds all this information and is stored in the new `TrackingOutputBuffer` class.

Tests are in `ItaniumDemangleTest.cpp`.

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.
