[Clang] Stop changing DC when instantiating dependent friend specializations (#139436)

Since 346077aa, we began using the primary template's lexical
DeclContext for template arguments in order to properly instantiate a
friend definition.

There is a missed peculiar case, as in a friend template is specialized
within a dependent context. In this scenario, the primary template is
not a definition, whereas the specialization is. So the primary
template's DeclContext doesn't provide anything meaningful
for instantiation.

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.
