lib: eliminate reduce-left from n-ary math ops.
Using reduce-left is inefficient; it conses up a list.
We can decimate the stacked arguments without consing.
* lib.c (nary_op): Replace reduce_left with iteration.
(nary_simple_op): New function, variant of nary_op
useable by functions that have a mandatory argument
passed separately from the argument list.
(minusv, divv): Replace reduce_left with iteration.
(maxv, minv): Replace reduce_left with nary_simple_op.
(abso_self): New static function.
(gcdv, lcmv): Replace reduce_left with nary_op.
* lib.h (nary_simple_op): Declared.
