I figured out;
'8' means that converting byte to bit.
'3' means that upper 3 bits of table_map is for special usage.
PARAM_TABLE_BIT, OUTER_REF_TABLE_BIT, and RAND_TABLE_BIT are
used for extract the special bits above.

Now I think;
As far as 'table_map' is 64bits, it's impossible to join
over 61 tables.

But I'd like to do it!! What can I do ???
