<pre>Consider the following code.
====
void g(void);
void h(void);
static void f(void)
{
static int i;
if (!i) {
i = 1;
h();
}
g();
}
int main(void)
{
f();
f();
}
====
Clang inlines `f()` but repeats the `!i` check. Expected result:
====
int main(void)
{
h();
g();
g();
}
====
which is the result when I manually inline `f()`.</pre>
