Use EnumType::getDecl() to get to the EnumDecl, then EnumDecl::enumerator_begin()/EnumDecl::enumerator_end() to iterate over the enumerators, each of which has a name and a value.

FieldDecl is a ValueDecl, which has ValueDecl::getType(). Then use ->getAs<EnumType>() to see if it has enumeration type.
