* Remove all traces of the long gone value restriction
We remove the value check since it has only been used by one `damli` command.
We also remove the constant folding from the DAML-LF simplifier. It is more
likely to diverge from the semantics of the interpreter than to do any good.
* Make hlint happy
This was used by the old DAML-LF based record constructor/projection
inliner. We'bve recently replaced by an inlining mechanism which is part
of the conversion from GHC Core to DAML-LF.
