0.8alpha.0.23:
	Fix a couple of the CLOS bugs that have been accumulating:
	... make :ALLOCATION :CLASS slots behave as they should in slot
		inheritance and class redefinition.
	Slightly unKLUDGEify the %SET-SYMBOL-VALUE implementation
	... do it the same way whether building with #!+SB-THREAD or
		not, so at least it's ugly once and only once.
