Ancestors: Compiler-topa.302

Revert two methods from Compiler-eem.300 because they work on a stack interpreter but not on a context interpreter (VM crash).

  The compiler guarantees that any copied values come before all local temps.
  So on closure activation we only need to push nils for the remaining temporaries."
