Log Message:
1.0.17.32: faster ADD-METHOD to PRINT-OBJECT
	The basic idea here is reducing the number of functions whose
	discriminating function and effective method cache are 
	precomputed; in particular, to reduce the number where users can 
	both legitimately define their own methods, and where a large 
	number of methods will be applicable to different classes.

	The biggest culprit in both of those categories is the 
	PRINT-OBJECT generic function, which would recompute its entire
	dispatch structure every time any method was added or removed.
	So, turn off precomputation for names in the CL package; deal 
	with the bootstrap metacircles that that provokes; special-case
	PRINT-OBJECT in COMPUTE-DISCRIMINATING-FUNCTION so that we can 
	always print certain critical pieces of infrastructure; 
	also, warn the user if they break our assumptions in 
	PRINT-OBJECT's specialization.

	Fix one broken "how did it ever work" test.
