* interp/g-opt.boot ($VMsideEffectFreeOperators): Remove CGREATERP
and GGREATERP. Add VM-level complex number operators.
* interp/lisp-backend.boot: Expand them.
* algebra/gaussian.spad.pamphlet (ComplexCategory): Use VM form
instead of Lisp level forms.
* algebra/pfr.spad.pamphlet (PartialFraction): Likewise.
* algebra/si.spad.pamphlet (SingleInteger): Likewise.
* algebra/symbol.spad.pamphlet (Symbol): Likewise.
