gnu-empty-struct, gnu-struct-without-named-member, and
gnu-only-flexible-array-member are all variants of the same extension
(allowing structs without a named member); it probably makes sense to put
them all under gnu-empty-struct.

gnu-folding-initializer-constant and gnu-folding-integer-constant are also
variants of the same extension (along with ext_vla_folded_to_constant)

gnu-redeclared-class-member probably shouldn't have "gnu" in the name; it's
not really an intentional extension.

(This isn't a formal review; please continue to submit patches as you have
been doing.)
