more funky &REST smartness

  Extend the earlier VALUES-LIST optimization for &REST arguments
  into other operations as well. For starters:

    CAR
    ELT
    ENDP
    FIRST
    IF
    LENGTH
    LIST-LENGTH
    NTH

  All of these can now access the hidden &MORE context when given a &REST
  argument that is not used by other operations, making it possible for the
  compiler to elide the entire rest-list allocation in those cases.
