	Output curried functions for data constructors
	----------------------------------------------
			(incomplete)

The idea here is to output code for the *curried* version of
the worker of a data constructor, so that the worker can be
treated as a first-class citizen elsewhere in the compiler.
In particular, it doesn't need to be a "hasNoBinding" thing,
which are the subject of a number of nasty hacks.

These changes only do the business for the code gen route
via AbstractC.  Remaining to do: the byte code generator.

Idea: move the byte-code gen to STG code, and inject the
curried data-constructor workers at the STG stage.


	I hope the changes here won't make
	anything stop working.  For now, constructor
	workers remain "hasNoBinding" things.
