New function: isecp.

* eval.c (eval_init): Register isecp intrinsic.

* lib.c (isecp): New function.

* lib.h (isecp): Declared.

* stdlib/compiler.tl (lambda-apply-transform,
dump-compiled-objects): Use isecp instead of isec, since the
actual intersection of symbols isn't needed, only whether it
exists.

* txr.1: Documented.

* stdlib/doc-syms.tl: Updated.
