  1. [LV] Use SCEV to check if minimum iteration check is known. 

    Use SCEV to check if the minimum iteration check (TC < Step) is known to
be false.

This is a first step towards addressing
llvm#111098. To catch
the exact case from the issue, we need to do extra work to make sure the
wrap flags on the shl are preserved and used by SCEV.
