    Generalize equality of heap_lang so it works on any value. · 8111cab0

    This is more consistent with CAS, which also can be used on any value.
    Note that being able to (atomically) test for equality of any value and
    being able to CAS on any value is not realistic. See the discussion at
    https://gitlab.mpi-sws.org/FP/iris-coq/issues/26, and in particular JH
    Jourdan's observation:
      I think indeed for heap_lang this is just too complicated.
      Anyway, the role of heap_lang is not to model any actual
      programming language, but rather to show that we can do proofs
      about certain programs. The fact that you can write unrealistic
      programs is not a problem, IMHO. The only thing which is important
      is that the program that we write are realistic (i.e., faithfully
      represents the algorithm we want to p
    This commit is based on a commit by Zhen Zhang who generalized equality
    to work on any literal (and not just integers).
