chenglin.bi dd31a3b3a5 [InstCombine] fold icmp of the sum of ext bool based on limited range 
For the pattern `(zext i1 X) + (sext i1 Y)`, the constant range is [-1, 1].
We can simplify the pattern by logical operations. Like:

```
    (zext i1 X) + (sext i1 Y) == -1 -->  ~X & Y
    (zext i1 X) + (sext i1 Y) == 0  --> ~(X ^ Y)
    (zext i1 X) + (sext i1 Y) == 1 --> X & ~Y
```
And other predicates can the combination of these results:

```
    (zext i1 X) + (sext i1 Y)) != -1 --> X | ~Y
    (zext i1 X) + (sext i1 Y)) s> -1 --> X | ~Y
    (zext i1 X) + (sext i1 Y)) u< -1 --> X | ~Y
    (zext i1 X) + (sext i1 Y)) s> 0 --> X & ~Y
    (zext i1 X) + (sext i1 Y)) s< 0 --> ~X & Y
    (zext i1 X) + (sext i1 Y)) != 1 --> ~X | Y
    (zext i1 X) + (sext i1 Y)) s< 1 --> ~X | Y
    (zext i1 X) + (sext i1 Y)) u> 1 --> ~X & Y
```
