Mahmoud Al-Qudsi 5ad292328a Add dynamic clang completions via clang --autocomplete
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.

# Multiple versions are often installed as clang, clang-7, clang-8, etc.
# They won't be autoloaded, but once clang++ is used once, they'll gain completions too.
# This could potentially be moved to __fish_config_interactive.fish in the future.
# This pattern unfortunately matches clang-format, etc. as well.
