[clang] Implement CWG2877 "Type-only lookup for using-enum-declarator" (#95399) This patch implements 2024-05-31 resolution of a tentatively ready issue [CWG2877](https://cplusplus.github.io/CWG/issues/2877.html) "Type-only lookup for using-enum-declarator", which supersedes earlier [CWG2621](https://cplusplus.github.io/CWG/issues/2621.html) "Kind of lookup for `using enum` declarations". Now we perform type-only lookup (not to be confused with type-only context) for `elaborated-enum-declarator`. This is the same kind of lookup that elaborated type specifiers and base specifiers undergo. I also found out (and fixed) that one of our existing tests claimed that a dependent type can be used in `elaborated-enum-declarator`, but that's not the case: > The [using-enum-declarator](http://eel.is/c++draft/enum.udecl#nt:using-enum-declarator) shall designate a non-dependent type with a reachable [enum-specifier](http://eel.is/c++draft/dcl.enum#nt:enum-specifier)[.](http://eel.is/c++draft/enum.udecl#1.sentence-2)
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.
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.

The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
