[PATCH] D18712: [LoopUnroll] Fix the way we update DT after complete unrolling.

Generally, I think this change will be somewhat easier to follow if
you update the commit message to "this is the pre-unroll loop A, which
gets unrolled to this loop B, and these are the blocks X and Y we need
to fixup out of which the current technique leaves out X".

I realize that you have a test case, but reviewers are lazy people. :)
