	Don't do CPR w/w for constants
	------------------------------

We don't want to do a CPR split for a constant
function.  So if the worker will get no (value) args,
we disable the CPR transformation.

This infelicity exposed a buglet in the full laziness
transformation; we were floating an expression outside
an InlineMe context.   I've take the blunderbuss approach
now, of effectively disabling full laziness inside an
InlineMe.  Seems reasonable.
