0.9.13.1:
	Improve SAP ref/set VOPs, inspired by Alistair Bridgewater's
	  comments in #lisp:
	... MOV{S,Z}X can take EAs; don't bother with a temporary
	    (the equivalent VOPs for DATA-VECTOR-REF already did this;
	     so much for OAOO...);
	... take this opportunity to consolidate VOPs and shrink the core.
