Test case from gcc testsuite:
https://github.com/gcc-mirror/gcc/blob/master/gcc/testsuite/gcc.dg/tree-ssa/phi-opt-11.c
```cpp
int f(int a, int b, int c)
{
if (a == 0 && b > c)
return 0;
return a;
}
int g(int a, int b, int c)
{
if (a == 42 && b > c)
return 42;
return a;
}
int h(int a, int b, int c, int d)
{
if (a == d && b > c)
return d;
return a;
}
```

Any of these functions can be optimized to a function which returns `a`. I feel like there may be a duplicate of this issue.
