small optimisations in generated code for dynamic types, call _unify_ instead of _unify if only the boolean result is used, use _bind_global_type_pattern_var_n with int type_var_n instead of_bind_global_type_pattern_var with (TypeVar type_var_n)

rename label _Nothing as _None in the generated code, and _!Nothing,_#Nothing and _|Nothing in the compiler to _!None,_#None and _|None

refactor, add type MemberDefault, use it for field me_default_implementation instead of Optional MacroMember

check if _SystemEnumStrict is imported (instead of _SystemStrictLists) for strict and unboxed list generators (prevents compiler crash)

add function compare_members_of_exported_classes to compare
number of members of class definitions in definition and implementation module earlier,
stop checking after checkIclInstances if an error has occurred,
both to prevent compiler crashes for incorrect programs

add type constraints in constructors and function arguments with universal quantifier (from iTask branch)

change GenericInfo

don't generate type representation in TD; functions,
use TypeCodeConstructor and TD_ constructors instead of TypeCodeConstructor.. functions

adjust imports

(to have fewer differences with the haskell frontend branch)

consecutive, use a loop to initialise these types and expressions

observation typeing)

report error if dynamics are used if dynamics are not enabled,
to prevent crashes while compiling

(will break dynamics on disk)

The distinction between TypePatternVars and TypeVars is not really
necessary.

clean-up and renamed functions from StdDynamic
