Use clang/clang++'s own autocompletion support to complete arguments. It is rather convoluted as clang generates autocompletions for a portion of the current token rather than the entire token, e.g. while `--st` will autocomplete to `--std=` (which is fine by fish), `--std=g` will autocomplete to `gnu...` without the leading `--std=` which breaks fish' support for the completion. Additionally, on systems where clang/clang++ is the system compiler (such as FreeBSD), it is very often for users to invoke a newer version of clang/clang++ installed as clang[++]-NN instead of clang. Using a monkey-patched version of `complete -p` to support that without breaking (future) completions for commands like `clang-format`. Closes #4174.
