flag types defined as unions
The risc-v abi needs to know if a type is defined as a union or not. We cannot use nunion to obtain this information because the risc-v abi made the unfortunate decision of treating union { int i; } differently from int i; So, instead, I introduce a single bit flag 'isunion'.
