	* decode.scm (-distinguishing-bit-population): Significantly
	improve popularity heuristic.  Renamed from
	(-mask-bit-population): Gone.
	(-population-above-threshold): Sort new bit numbers in order of
	popularity.
	(-population-top-few): Allow up to three more bits to be selected
	than requested.  Correct selection order to prefer better bits.
	Correct bug in fewer-than-requested case.  Keep threshold as
	floating-point.
	(decode-best-get-bits): Pass also the insn-values.
	
	* utils-sim.scm (-gen-decoder-switch): Add comment suggesting a
	future optimization.
	
	* utils.scm (message): Format nested lists better.
