Support autovectorization of diamond loops.

This CL enables predicated autovectorization of loops with
control flow, currently only for simple diamond pattern ones:

                header------------------+
                  |                     |
             diamond_hif                |
                /   \                   |
     diamond_true  diamond_false        |
                \   /                   |
              back_edge                 |
                  |                     |
