[llvm] r225159 - Fixed a bug in memory dependence checking module of loop vectorization. The following loop should not be vectorized with current algorithm.

Hi Jiangning,

I think is causing a test failure,

FAIL: LLVM :: Transforms/LoopVectorize/loop-vect-memdep.ll (10297 of 12169)
******************** TEST 'LLVM ::
Transforms/LoopVectorize/loop-vect-memdep.ll' FAILED

Apologies in advance if I've messed up finding the cause of this.

Cheers,
Charlie.
