If you find that the partition id calculation for partitioned array is "unpredictable"

Please remove the bitwidth reduction pass here: https://github.com/zslwyuan/Light-HLS/blob/master/Tests/Light_HLS_Top/Light_HLS_Top.cc#L310

The problem is caused by the address calculation procedure which might be optimized by bitwidth reduction pass. Bitwidth truncation/extension might make LLVM ScalarEvolution difficult.
