      Support function pointers and use a state monad in the frontend. · b2109c25
      Robbert Krebbers authored
      Important changes in the core semantics:
      * Types extended with function types. Since function types are a special kind
        of pointer types, types now have an additional mutual part called "ptr_type".
      * Pointers extended with function pointers. Theses are just names that refer
        to an actual function in the function environment.
      * Typing environments extended to assign argument and return types to function
        names. Before we used a separate environment for these, but since the
        argument and return types are already needed to type function pointers, this
        environment would appear in pretty much every typing judgment.
      
      As a side-effect, the frontend has been rewritten entirely. The important
      changes are:
      
      * Type checking of expressions is more involved: there is a special kind of
        expression type corresponding to a function designator.
      * To handle things like block scoped extern function, more state-fullness was
        needed. To prepare for future extensions, the entire frontend now uses a
        state monad.

      More accurate formalization of integer ranks. · da7a14bb
      Robbert Krebbers authored
      Integers with the same size, are no longer supposed to have the same rank. As a
      result, the C integer types (char, short, int, long, long long) are different
      (and thus cannot alias) even if they have the same size. We now have to use a
      more involved definition of integer promotions and usual arithmetic conversions.
      However, this new definition follows the C standard literally.
