Calculation of Class::NumTypeArguments() is reimplemented so that it does
no require separate calculation of Class::NumOwnTypeArguments().
Number of own type arguments is no longer stored in Class, and has_pragma
bit is moved into state_bits.
This simplifies overall calculation and does not require to keep both
num_type_arguments and num_own_type_arguments. This also allows us to add
up to 15 more flag bits to Class.
