Jonas Maebe 37aa2d8443 + full support for sets on the JVM target
o sets of enums are handled as JUEnumSet instances, others as JUBitSet
     derivatives (both smallsets and varsets, to make interoperability with
     Java easier)
   o special handling of set constants: these have to be constructed at run
     time. In case of constants in the code, create an internal constsym to
     represent them. These and regular constsyms are then aliased by an
     another internal staticvarsym that is used to initialise them in the
     unit initialisation code.
   o until they are constructed at run time, set constants are encoded as
     constant Java strings (with the characters containing the set bits)
   o hlcgobj conversion of tcginnode.pass_generate_code() for the genjumps
     part (that's the only part of the generic code that's used by the JVM
     target)
   o as far as explicit typecasting support is concerned, currently the
     following ones are supported (both from/to setdefs): ordinal types,
     enums, any other set types (whose size is the same on native targets)
   o enum setdefs also emit signatures
   o overloading routines for different ordinal set types, or for different
     enum set types, is not supported on the JVM target

of arrays, so that's the same for all array kinds. Only the type of the final
dimension matters.
org is the current array, new is a newly allocated array of the

This routine uses the intermediate levels from the old array if possible so
that an unchanged array remains in the same place.
