[PATCH] A tweak for debug_ops_vector

[Marek Polacek]

I've been playing with reassoc recently and what bothers me is that
dump_ops_vector doesn't print a newline after each element, so it prints
e.g. "Op 0 -> rank: 5, tree: a_1(D)Op 1 -> rank: 4, tree: c_3(D)" which
isn't really all that readable to me.

Bootstrapped/regtested on x86_64-linux, ok for trunk?

        * tree-ssa-reassoc.c (dump_ops_vector): Print newline after each
        ops element.
