Thanks for the review.

Updated patch to handle exact division and exact log2. We were handling exact division and exact log2 for ashr in instsimplify, and not for lshr.

Now we are handling for both. Updated test cases which includes constants to the extreme limit and not something random in between.
Also took care of 80 lines clang-format. :)

Please help in reviewing the patch.
