0.8.0.78.vector-nil-string.7:
	The beginnings of the payoff: being sufficiently irritated by
	the baroque intertwinings of the different places where array
	types have to be specified, here is a beginning of a
	rationalization.
	... make *SPECIALIZED-ARRAY-ELEMENT-TYPE-PROPERTIES* a master
		value, and derive three other compiler-internal lists
		from it.  (net win so far: 3)
	... but because it's made earlier so that we can use it as a
		master value, SPECIFIER-TYPE gives unknown types;
		a new file (and corresponding cold-init function)
		fixes up unknown types (and for primitive-types too)
	... there are still plenty of places left where array logic
		isn't derived from *SAETP*; they will be worked on.
