tree-ssa-dce.c (remove_dead_statement): When removing a dead control statement... · 0a180c0e

        * tree-ssa-dce.c (remove_dead_statement): When removing a dead
        control statement, handle all three special cases in the same
        manner as they all have the same desired solution.  No longer
        special case edge flag updating when the post dominator is
        the exit block.
