0.8.9.10:
	DYNAMIC-EXTENT &REST lists.
	... much as per CSR sbcl-devel 2004-03-29;
	... alter listify-rest-args VOPs on non-x86 to meet the new use
		(don't do anything yet with the DX parameter)
	... note concerns over stack manipulation in x86 DX allocation

	This version compiles and passes tests on x86 and alpha (modulo
	one unrelated bugfix, coming soon)
