Use b4_type_names for the union type.

The union used to compute the size of the variant used to iterate over the
type of all the symbols, with a lot of redundancy.  Now iterate over the
lists of symbols having the same type-name.

	* data/lalr1.cc (b4_char_sizeof_): New.
	(b4_char_sizeof): Use it.
	Adjust to be called with a list of numbers instead of a single
	number.
	Adjust its caller for new-line issues.
