Missed tail call optimization when local address could escape but not on the condition:
void f(void);
void f1(int *);
void g(int i, int j)
{
if (j)
return f();
return f1(&i);
}
This might be a reduced testcase from fold_binary to fold_build2 where we have this issue, but I have
not looked through all of the conditionals to see if this is true.
