The information whether a specific argument is vararg or fixed is currently stored separately from all the other argument information in ArgFlags. This means that it is not accessible from CCAssign, and backends have developed all kinds of workarounds for how they can access it after all. Move this information to ArgFlags to make it directly available in all relevant places. I've opted to invert this and store it as IsVarArg, as I think that both makes the meaning more obvious and provides for a better default (which is IsVarArg=false).
