[clang] fix regression printing constructor/destructor names (#155688)

This makes the type printer not qualify constructor and destructor
names. These are represented as canonical types and the type printer is
used, but unlike canonical types which we normally print as fully
qualified, the expected behaviour for declaration names is for them to
be unqualified.

Note that this restores the behaviour pre #147835, but that is still
broken for the constructor names of class templates, since in that case
the injected class name type is used, but here the type printer is
configured to also print the implicit template arguments.

No release notes since this regression was never released.

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
