Marcelo Domínguez f92d84cc6e Initial naive implementation using Symbols to represent autodiff modes (Forward, Reverse)
Since the mode is no longer part of `meta_item`, we must insert it manually (otherwise macro expansion with `#[rustc_autodiff]` won't work).

This can be revised later if a more structured representation becomes necessary (using enums, annotated structs, etc).

Some tests are currently failing. I'll address them next.
