The `UnrollMaxBlockToAnalyze` parameter is used at the stage when we have no
information about a loop body BB cost. In some cases, e.g. for simple loop
```
for(int i=0; i<32; ++i){
D = Arr2[i*8 + C1];
Arr1[i*64 + C2] += C3 * D;
Arr1[i*64 + C2 + 2048] += C4 * D;
}
```
current default parameter value is not enough to run deeper cost analyze so the
loop is not completely unrolled.
