RTTI improvements for Java backend. io.write/3 works for some simple types

RTTI improvements for Java backend.  io.write/3 works for some simple types
(builtin types and non-existential d.u. types).

compiler/mlds_to_java.m:
        Fix problem with cyclic RTTI definitions.  Initialisers could refer to
        other RTTI structures which weren't yet allocated, leading to fields
        being null.  The fix is to allocate all top-level RTTI objects first
        and initialise in a second phase.

java/runtime/DuExistInfo.java:
java/runtime/DuExistLocn.java:
java/runtime/DuFunctorDesc.java:
java/runtime/EnumFunctorDesc.java:
java/runtime/ForeignEnumFunctorDesc.java:
java/runtime/TypeClassConstraint.java:
java/runtime/TypeClassDeclStruct.java:
java/runtime/TypeClassId.java:
java/runtime/TypeCtorInfo_Struct.java:
java/runtime/TypeInfo_Struct.java:
        Separate constructors into constructors for the initial allocation,
        and an `init' method to fill in the fields.

java/runtime/MethodPtr.java:
        Use variadic method support to simplify semidet_call_* and
        result_call_* in rtti_implementation.m.

library/builtin.m:
        Make Java definitions of builtin.unify/2 and builtin.compare/3 call
        rtti_implementation.generic_unify and generic_compare.

library/private_builtin.m:
        Add missing MR_TYPECTOR_REP_FOREIGN_ENUM{,_USEREQ} constants
        for C# and Java.

library/rtti_implementation.m:
        Fix and add missing Java versions of many foreign_procs.

        Add more attributes to foreign_procs.

        Clean up the code a bit (fewer casts and ^ field access functions).

README.Java:
        Bump Java version requirement to J2SE 1.5 or higher.
