[PATCH] Fix iteration over loads in SLP optimize

[Richard Biener]

I've made a typo when refactoring the iteration over all loads in
the SLP graph.  Fixed.

Bootstrapped on x86_64-unknown-linux-gnu, testing in progress.

        * tree-vect-slp.c (vect_optimize_slp): Fix iteration over
        all loads.
