__attribute__((fallthrough)) can't simply be ignored
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.
