nit: this function could be useful for other checks so I'd like the comment to
be a bit more clear:
- We do not have to mention "match the Expr spelling" since it is unrelated to
this function.
- We could make it clear that this function follows the macro chain, where all
macros are "simple"---having no arguments and are defined as an identifier of
another macro. The function returns the first non-"simple" macro along the
chain or nullptr if the chain is empty.
