0.8.2.10:
	Implement SB-EXT:CODE-DELETION-NOTE, at least partly for
	pfdietz' benefit
	... I'm too nice, really I am;
	... we're going to need COERCE-TO-CONDITION in the
		cross-compiler;
	... extract (somewhat bogusly) format control and arguments from
		the condition in the SIMPLE-CONDITION case, so that warm
		init doesn't print every compiler note in long form.
