0.6.9.11:
	more cleanups of optimization policy machinery..
	renamed CSPEED slot to COMPILATION-SPEED, and BREVITY slot to
		INHIBIT-WARNINGS, and got rid of other BREVITY refs
	STRUCTURE-OBJECT-based POLICY caues too many cold init hassles
		w/ COPY-POLICY and slot accessors. Use alists instead.
	Now PROCESS-OPTIMIZE-DECLARATION can look up qualities
		directly in *POLICY-BASIC-QUALITIES*.
