Amusingly, this new enumerator overflows the bitfield used to store the Syntax
value:
/// The number of expression arguments this attribute has.
/// The expressions themselves are stored after the object.
unsigned NumArgs : 15;
/// Corresponds to the Syntax enum.
unsigned SyntaxUsed : 2;
Yet more amusingly, extending this bit-ield to three bits breaks things, as
does replacing the one source of AS_Syntax attributes with AS_GNU :)
