This supports __powidf2 by means of a double wrapper for already existing f7_powi (renamed to __f7_powi by f7-renames.h). It tweaks the implementation so that it does not perform trivial multiplications with 1.0 any more, but instead uses a move. It also fixes the last statement of f7_powi, which was wrong. Notice that f7_powi was unused until now.
