0.pre7.86.flaky7.17:
	(still works as well as before, still fails in
		pathnames.impure.lisp the same way as before, since all
		the changes are still only preparation for a real fix)
	removed various INLINEs in ir1util.lisp, to ease debugging and
		because I hope sometime next year to be doing some
		profiling on the compiler (so that if they really need
		to be inlined, I should soon find out)
	making FIND-INITIAL-DFO recognize closure dependencies...
	...rearranged DFO-SCAVENGE-DEPENDENCY-GRAPH in preparation for
		walking through LAMBDA-REFERS-TO-VARS as well as
		LAMBDA-CALLS
