Since, by definition, we ignore ignored attributes, it's completely
useless to keep a list of those (which needs to be updated each time
gcc, clang, ... add new attributes, wich is quite often).
Let's just keep things simple and stop to try to make a distinction
between 'unknown' and 'ignored' attributes. We can then only care
about the attributes we (need to) handle and simply ignore the others
ones since we don't do anything with them anyway.
