  (write-arities): Emit representations into the arities section.

* module/system/vm/debug.scm (arity-definitions): Read representations.

* module/system/vm/frame.scm (<binding>): Add representation field and
  binding-representation getter.
  (available-bindings): Pass representation to make-binding.
  (frame-binding-set!, frame-binding-ref, frame-call-representation):
  Pass representation to frame-local-ref / frame-local-set!.

* test-suite/tests/rtl.test: Update definition instructions.

* module/language/cps/slot-allocation.scm ($allocation): Add
