Tim Shen	63f244c4f4	[SCEV] Re-apply r335197 (with Polly fixes). Summary: This initiates a discussion on changing Polly accordingly while re-applying r335197 (D48338). I have never worked on Polly. The proposed change to param_div_div_div_2.ll is not educated, but just patterns that match the output. All LLVM files are already reviewed in D48338.

[SCEV] Re-apply r335197 (with Polly fixes).

Summary:
This initiates a discussion on changing Polly accordingly while re-applying r335197 (D48338).

I have never worked on Polly. The proposed change to param_div_div_div_2.ll is not educated, but just patterns that match the output.
