  	Fix a too-vigorous export bug

  	[this is the Ian Lynagh -O2 bug]
  
  CoreTidy didn't filter the rules that it exports, so it
  exported some that mentioned Ids on the *left* hand side
  that are not exported.  So an importing module fell over.
  
  The fix is simple: filter the exposed rules.   On the way
  I tidied up CoreFVs a little.
