In the Decompiler::HandleTranslationUnit method we abuse clang::tooling to call clang on an empty file, each time a new Function is decompiled. To do this we use clang::tooling's CommonOptionParser, which appends the names of the parsed files to a static cl::list. The fact that this list is static, means that it is never cleaned between calls to DecompilationPass, which means that at each successive call clang::tooling thinks we have more and more input files, meaning that it creates multiple translation units. For each translation unit we run a DecompilationAction, hence we emit multiple identical copies of the same function. To disable this we have to create CommonOptionParser only once, making it static as well.
