  [LSR] Add test coverage for ICmpZero cases involving urem RHS

For the moment, we're pretty conservative here.  My motivating case is the vscale one (as that is idiomatic for scalable vectorized loops on RISCV).  There are two obvious approaches to fixing this, and I tried to add reasonable coverage for both even though I'll likely only fix one.
