One more thing, we miss a sibcal optimization due to this:
int i;
int g(void) __attribute__((pure));
int f()
{
int t = i;
int t1 = g();
i = t;
return t1;
}

We just don't generate any RTL for "i = i".
The optimization for f in comment #0 happens in combine for 3.4.0, so maybe
fold could do it, I don't
know.

Three more cases:
void f1(int *i)
{
*i = *i;
}
int j;
void f2()
{
j = j;
}
int *k;
void f3()
{
*k = *k;
}
