 Immutable statics are always considered inlineable unless marked with
 `#[inline(never)]`. It is undefined whether two different inlineable statics
 have the same memory address. In other words, the compiler is free to collapse
 duplicate inlineable statics together.

 There are three different types of inline attributes:
