realpow_divide -> power_divide

wenzelm [Tue, 12 Sep 2006 12:16:17 +0200] rev 20513
Efficient term substitution -- avoids copying.
moved here from term.ML;
added instantiate_maxidx;
wenzelm [Tue, 12 Sep 2006 12:12:57 +0200] rev 20512
ctyp: maintain maxidx;
cterm_match: tight maxidx for substitution;
instantiate: determine maxidx from insts -- major performance improvement;
moved term subst functions to TermSubst;
tuned;
wenzelm [Tue, 12 Sep 2006 12:12:55 +0200] rev 20511
removed obsolete aconvs (use eq_list aconv);
tuned aconv --- more efficient on identical subterms;
moved term subst functions to term_subst.ML;
wenzelm [Tue, 12 Sep 2006 12:12:53 +0200] rev 20510
tuned eq_list;
