[PATCH] Sema: Treat zero sized arrays as flexible array members

[Andrea Di Biagio]

Thanks for this patch.

I am not knowledgeable enough in this area to give a LGTM, but personally I like this approach.
I always thought that GCC was too permissive in general when it came to using zero-length arrays.
I agree that we should allow declaring a zero-length array as the sole element of a structure. I am not sure if it makes sense to have a zero-length array in a union.
