  -----------
  [llvm] Remove the Legacy PM Hello example (#95708)

The Legacy PM was deprecated for the optimization pipeline in LLVM 14
[1] (the support was removed altogether in the following release). This
patch removes the original Hello example that was introduced to
illustrate the Legacy PM. The Hello example no longer works and hence is
deleted. The corresponding documentation is also removed.

Note, Hello example for the new PM is located in
  * llvm/lib/Transforms/Utils/HelloWorld.cpp
  
and documented in
  * WritingAnLLVMNewPMPass.rst.
