llvmPackages_5: drop

While using very old compilers is a fair usecase, it induces a maintenance churn as
we collect more and more LLVM versions for the LLVM maintainers.

Especially when we need to backport uniform changes to the whole tree,
furthermore, it consumes and waste CI resources.

-        The Clang project provides a language front-end and tooling
-        infrastructure for languages in the C language family (C, C++, Objective
-        C/C++, OpenCL, CUDA, and RenderScript) for the LLVM project.
-        It aims to deliver amazingly fast compiles, extremely useful error and
-        warning messages and to provide a platform for building great source
-        level tools. The Clang Static Analyzer and clang-tidy are tools that
-        automatically find bugs in your code, and are great examples of the sort
-        of tools that can be built using the Clang frontend as a library to
-        parse C/C++ code.

-      The LLVM Project is a collection of modular and reusable compiler and
-      toolchain technologies. Despite its name, LLVM has little to do with
-      traditional virtual machines. The name "LLVM" itself is not an acronym; it
-      is the full name of the project.
-      LLVM began as a research project at the University of Illinois, with the
-      goal of providing a modern, SSA-based compilation strategy capable of
-      supporting both static and dynamic compilation of arbitrary programming
-      languages. Since then, LLVM has grown to be an umbrella project consisting
-      of a number of subprojects, many of which are being used in production by
-      a wide variety of commercial and open source projects as well as being
-      widely used in academic research. Code in the LLVM project is licensed
-      under the "Apache 2.0 License with LLVM exceptions".
