	* opt/fcontract.sml (dropcstargs): replace constant args by the constant.

	* opt/fixfix.sml (curry): correctly handle "imposible" cases.

	* opt/collect.sml: completely revisited:  no distinction between
	  internal/external uses, dead-code elimination done right away.  This
	  makes fcontract a little simpler.

	* opt/fcontract.sml (inline): do simple inlining only for non-isrec
	  functions (to ensure we never silently turn external uses into internal
	  uses) and correspondingly change the agressive inlining to inline
	  non-inlinable functions as long as its their last use.
	(dropargs): new functions to drop unused arguments.

	* opt/optutils.sml: trying to reuse code between fixfix and fcontract.

	* opt/collect.sml (called): added for eta-expand.

	* opt/fcontract.sml (inline): allow single inlining of FK_FCT.

	* lsplit/ls-inline.sml: don't call lcontract anymore.

	* cps/cpstrans.sml (spillOut): fix from Zhong.

	* cpsopt/cpsopt.sml: use Control.CG.cpsopt and fold over it.

	* main/flintcomp.sml: use Control.FLINT.phases and fold over it.

	* opt/fixfix.sml (curry): use Control.FLINT.maxargs to bound the uncurrying
