Whitney Tsang 0fee91a187 [LoopUnroll] Add a test case for rG7873376bb36b. 
rG7873376bb36b fixes a build failure for allyesconfig.

The problem happened when the single exiting block doesn't dominate the
loop latch, then the immediate dominator of the exit block should not be
the exiting block after unrolling. As the exiting block of
different unrolled iteration can branch to the exit block, and the ith
exiting block doesn't dominate (i+1)th exiting block, the immediate
dominator of the exit block should not the nearest common dominator of
the exiting block and the loop latch of the same iteration.
