Approaches like that as well as the in-tree pgrminclude work by "I
removed the #include and it still compiled fine", which can be
unreliable. IWYU on the other hand has the compiler tracking where a
symbol actually came from, and so if it says that an #include is not
used, then it's pretty much correct by definition.
