Simplification for (A ==/!= B) &/| (((cast)A) CMP C)

[k-arrows]

Example:
https://godbolt.org/z/Pr8T7xsMz

bool f(int a)
{
    bool t = a == 0;
    short t1 = a;
    bool t2 = t1 >= 3;
    return t & t2;
}

bool g(int b)
{
    bool t = b == 3;
    short t1 = b;
    bool t2 = t1 >= 3;
    return t | t2;
}

The example above is taken from the following:
