needed if a case function is generated

because that is what transCase False No will do,
rename transCase as transform_active_root_case and remove is_active and
change optional aci to aci, because it is always called with True (Yes aci),
rename possibly_generate_case_function as transform_active_non_root_case,
changes in layout

 								-> skip_over this_case

more than one recursive call is fused with a case that is not at the root,
previously the recursive calls could get different function indices, causing
the compiler to crash

could only fail in case of a kind error which is already detected
elsewhere

extended unused args analysis
improved strictness for case instantiation
dead code removal

FI_IsNonRecursive from partition.icl and trans.icl
to syntax.dcl, added FI_IsUnboxedListOfRecordsConsOrNil
to mark instances of unboxed lists of records generated
in type.icl

fix bug in fusion of overloaded cons constructor,
enable producers with overloaded list pattern match

a lazy or boxed strict list constructor

to fix a bug if type synonyms are used and a .tcl file
is generated

Fix bug with arity checks;
Fix bug with unification with universal quantors.

simplify matching requirements for trivial functions

better free var info for cases
clear info in heap for casefun generation

new recursive fun implementation
use FailExpr for neverMatchingCase
strip and dump commandline args
