fix @slot-ref / @slot-set! compilation

* module/language/tree-il/compile-glil.scm: Add primcall compilers for
  @slot-ref and @slot-set.

* module/language/tree-il/optimize.scm (add-interesting-primitive!): New
  export. Creates an association between a variable in the current module
  and a primitive name.

* module/oop/goops.scm: Rework compiler hooks to work with tree-il and
  not ghil.
