0.8.0.59:
	Make VALUES derive type optimizer accurate:
	... since we have this nice interpretation of VALUES types, use
		it in the VALUES derive-type optimizer -- we will return
		exactly	as many values as VALUES has arguments;
	... fix the bugs that this reveals in sbcl; :-)
	... enables us to detect more bogosity: test for some more type
		mismatches being caught.
	... (relatedly) fix one more duplicate definition in
		sb-bsd-sockets
	Array initializer type warning fix:
	... don't do (csubtypep (ctype-of x) eltype), because that's wrong
		for e.g. X = #\a and eltype being STANDARD-CHAR; use
		CTYPEP instead.
