Correctly check if a cursor is a declaration before returning its location/range in clang_getCursorLocation()/clang_getCursorExtent(). This fixes a horrible bug reported in

<rdar://problem/7961995> and <rdar://problem/7967123> where declarations with attributes
would get grossly annotated with the wrong tokens because the attribute would be interpreted
as if it was a Decl*.
