        * tree-ssa-ifcombine.c: Include rtl.h and tm_p.h.
        (ifcombine_ifandif): Handle cases where maybe_fold_and_comparisons
        fails, combining the branches anyways.
        (tree_ssa_ifcombine): Inverse the order of the basic block walk,
        increases the number of combinings.
        * gimple.h (gsi_start_nondebug_after_labels_bb): New function.
