add constructors PE_Matches and IsConstructor in module syntax

add instance member types in definition modules

No commit message

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..

No commit message

because OBJECT, CONS and FIELD have this kind and are the only types using generic info

call exported generic instances directly

in genericsupport

existential or universal quantifier

add bimap instances for standard generic types to compiler

change toGenericFrom and fromGenericto to fromGeneric and toGeneric

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

can crash because arguments can be incorrectly analyzed as unused

now sd_field_nr used instead of fs_index
