<pre>Merging data sections by ICF is not usually safe because it breaks an
assumption pointer equality. However, section A is a substring of section B,
and if A's starting position in B is not zero, we can merge the two without
breaking the pointer equality. I don't know how much we can save with it, but
it may worth investigating.</pre>
