	Undo an earlier hack in postInlineUnconditionally
	-------------------------------------------------

In an earlier era I made postInlineUnconditionally rather less
aggressive; it didn't inline even trivial things unless they
occurred just once.  THis was a hack designed to avoid rules
unexpectedly not firing.  But now we have much more control
over rules, through the phase numbering stuff, so I can undo the
hack.

Well, so I believe.  Manuel, yell if your rules stop working!
