        * basic-block.h (first_insn_after_basic_block_note): Declare.
        * flow.c (first_insn_after_basic_block_note): Define.  Moved
        from...
        * ssa.c (first_insn_after_basic_block_note): Remove.
        * ssa-dce.c (find_inherently_necessary): Consider BARRIERs
        necessary.
        (ssa_eliminate_dead_code): Properly update the CFG and PHI
        nodes when we find a dead conditional branch.  Insert BARRIERs
        after any blocks with no successors, but which do not have
        any BARRIERs.
