Currently, sparse has the attribute 'fallthrough' in its list of known-but-ignored attributes (like almost every GCC's attributes). But this attribute is a statement attribute, something which is currently not supported (it's interpreted as the attribute of an empty declaration which doesn't play well with -Wdeclaration-after-statement). Fix this by stopping to consider this attribute as known. This will allow __has_attribute(fallthrough) to correctly play its role. Note: a more complete solution will need to parse this statement attribute and maybe be able to make the distinction between statement attributes, label attributes (also currently ignored), and type, function & variable attributes.
