Improve and refactor StgToCmm codegen for DataCons.
We now differentiate three cases of constructor bindings:
1)Bindings which we can "replace" with a reference to
an existing closure. Reference the replacement closure
when accessing the binding.
2)Bindings which we can "replace" as above. But we still
generate a closure which will be referenced by modules
importing this binding.
3)For any other binding generate a closure. Then reference
it.
Before this patch 1) did only apply to local bindings and we
didn't do 2) at all.
