      Clean up heap_lang and remove some FIXMEs. · 15058014
      Robbert Krebbers authored
      Notable changes:
      * I am now using the same names for the fields of the language record and the
        instances in heap_lang. In order to deal with shadowing, I have put all
        definitions in heap_lang.v in a module.
      * Instead of defining evaluation contexts recursively, these are now defined
        using lists. This way we can easily reuse operations on lists. For example,
        composition of evaluation contexts is just appending lists. Also, it allowed
        me to simplify the rather complicated proof of step_by_val as induction on
        the shape of contexts no longer results in a blow-up of the number of cases.
      * Use better automation to prove all lemmas of heap_lang.
      * I have introduced tactics to invert steps and to do steps. These tactics
        greatly helped simplifying boring parts of lifting lemmas.

      Step-indexed order on CMRAs · 780f6b82
      Robbert Krebbers authored
      * Remove the order from RAs, it is now defined in terms of the ⋅ operation.
      * Define ownership using the step-indexed order.
      * Remove the order also from DRAs and change STS accordingly. While doing
        that, I changed STS to no longer use decidable token sets, which removes the
        requirement of decidable equality on tokens.
