other item which can be decorated with an attribute.</p>
<p>It takes one argument which is any range of major or <code>major.minor</code> LLVM versions.</p>
<p>To use with enum variants or struct fields, you need to decorate the parent item with
the <code>#[llvm_versioned_item]</code> attribute, as this is the hook we need to modify the AST
of those items.</p>
