[InstCombine] sub(xor(x, y), or(x, y)) -> neg(and(x, y))
Summary:
```
Name: sub(xor(x, y), or(x, y)) -> neg(and(x, y))
%or = or i32 %y, %x
%xor = xor i32 %x, %y
%sub = sub i32 %xor, %or
=>
%sub1 = and i32 %x, %y
%sub = sub i32 0, %sub1
Optimization: sub(xor(x, y), or(x, y)) -> neg(and(x, y))
Done: 1
Optimization is correct!
