Function attributes relate to the function declaration they appear in. Sparse ignore most these attributes but a few ones have a semantic value: 'pure', 'noreturn' & 'externally_visible'. Due to how Sparse parse attributes and how these attributes are stored for functions, the attributes 'pure' & 'noreturn' are applied not to the function itself but its return type if the function returns a pointer. Fix this by extracting these attributes from the declaration context and ensure they're applied to the declarator.
