__attribute__((aligned)) is a little funny in that it's got multiple spellings
("align" and "aligned") and takes 0 or 1 arguments. I think this patch will
make us accept "__declspec(align)" and "__declspec(aligned(16))"; I
assume that the latter is wrong and the former might be wrong.
In either case, you should be able to filter these easily by checking the
identifier info on the parsed attribute, as well as whether it has an
argument. Please also test these possibilities.
