tests: Remove llvm2cpp, I'm pretty sure no one uses this.

-# This file defines a tcl proc to assist with testing the llvm2cpp. There are
-# no llvm2cpp specific test cases. Instead, it utilizes all the existing test
-# cases and makes sure llvm2cpp can run them. The basic idea is that we find
-# all the LLVM Assembly (*.ll) files, run llvm2cpp on them to generate a C++
-# program, compile those programs, run them and see if what they produce matches
-# the original input to llvm2cpp.
