[PATCH] Fix another leak and one uninitialized var read

[Jakub Jelinek]

Hi!

Another leak and another uninitialized var.
Testing in progress, ok for trunk if it passes?

        * tree-vect-loop.c (vect_transform_loop): Initialize
        check_profitability to false.

        * tree-predcom.c (try_combine_chains): Free the worklist vector
        at the end.
