Zhaoshi Zheng b8ce2355f6 [Unroll] Do NOT unroll a loop with small runtime upperbound 
For a runtime loop if we can compute its trip count upperbound:

Don't unroll if:
1. loop is not guaranteed to run either zero or upperbound iterations; and
2. trip count upperbound is less than UnrollMaxUpperBound
Unless user or TTI asked to do so.

If unrolling, limit unroll factor to loop's trip count upperbound.
