卜部昌平 6f27fa4f7d prefer class_serial over m_tbl 
Decades ago, among all the data that a class has, its method
table was no doubt the most frequently accessed data.  Previous
data structures were based on that assumption.

Today that is no longer true.  The most frequently accessed field
moved to class_serial.  That field is not always as wide as VALUE
but if it is, let us swap m_tbl and class_serial.
