The following testcase triggers an ICE on trunk when compiled with "-O2":
================================================
bool foo0(int) { return true; }
bool foo1();
void foo2(bool);
template<typename T> inline void bar1(T f)
{
if (f(0))
foo1();
}
template<typename T> void bar2(T f)
{
while (foo1())
{
foo2(foo1());
if (foo1())
bar1(f);
}
if (foo1())
bar1(f);
}
void baz()
{
bar2(foo0);
}
================================================
