before copying the producer, the type variables are modified
to use the type of the producer when updating the types in cases and lets,
otherwise a polymorphic type may be specialized, possibly causing a type error later

add constructors PE_Matches and IsConstructor in module syntax

adjust imports

add instance member types in definition modules

(to have fewer differences with the haskell frontend branch),
the conversion table for macros is not used after checking

but do not occur in the type of a dynamic pattern.
TempQDV is used for existential type variables in a dynamic pattern.

because function pointers for generated functions are stored in the Component,
they can be found without searching the new functions list

constructors with only type variable arguments occurring at most once,
these types can be optimized if they occur as an argument or result,
or as an argument of such a type, of a generic function (and a generic
variable is used by the type)

call instance functions for OBJECT, CONS and FIELD directly, with generic info

first all main instances are build, then all shorthand instances,
shorthand instances directly call the main instance (SK_Function instead of SK_Generic),
call toGeneric.. and fromGeneric.. functions directly if possible, instead of iso..

call exported generic instances directly

is used in a curried application of a case expression, to prevent
case's with applications that are be optimized.
Whether the producer is treated as a curried or normal producer is
determined during unfolding, PR_CurriedProducer is
used to mark producers for which this is allowed.

add bimap instances for standard generic types to compiler

of a case and is also used in another alternative,
these lets were not added to the list of lets closed by cases,
now they are, and the let will be reopened in the other alternative

backendpreprocess may number variables incorrectly, causing a crash
in backend.dll,
renamed VI_CaseVar to VI_CaseOrStrictLetVar

used and may cause the compiler to crash if generic definitions and
instances occur on a cycle of definition modules

{a & [i]= } expressions, instead of [i] a sequence of record and array
selections may be used. ending with an array selection

use UniqueSingleArraySelector for a![i] instead of NormalSelector and
add UniqueSingleArraySelectorUniqueElementResult

remove unused field stv_count in STE_BoundTypeVariable,
remove unused argument def_macros of type CollectedDefinitions
