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.
