Teach stack promotion to walk the CFG when a potential reuse of an allocation
is found to see if it can actually happen instead of just assuming it will.
This allows it to catch cases like
{{{
int i;
Foo f;
while (cond(i))
f = new Foo(i++);
return f.value;
}}}
where it previously wouldn't because a phi using the allocation would appear in
the condition block to propagate it to the use after the loop.
