This removes dead code from the vectorizer and makes a function static.
Bootstrapped / tested on x86_64-unknown-linux-gnu, applied.

* tree-vectorizer.h (get_initial_def_for_reduction): Remove.
* tree-vect-loop.c (get_initial_def_for_reduction): Make
static.
(vect_create_epilog_for_reduction): Remove dead code.
