[libc++][test] Raise a useful error when no -std=c++NN flag is found to work (#99423)

Recently ran into an issue with symptoms very similar to
https://github.com/llvm/llvm-project/issues/56816 while attempting to
build and test libc++ on NixOS. The error message is cryptic (just
`StopIteration`), which was very annoying to track down. The error at
least saying "hey your compiler's bad" would have saved me quite a bit
of time figuring out the issue.

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.
