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/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.

Some fixes to the Java back-end, to make it work again after
Zoltan's recent type class RTTI changes.
java/runtime/DuExistInfo.java:
Add a new field "exist_constraints" to the DuExistInfo type
and a corresponding argument to the constructor, to match
Zoltan's recent changes.
java/runtime/TypeClassId.java:
java/runtime/TypeClassMethod.java:
java/runtime/TypeClassDeclStruct.java:
java/runtime/TypeClassConstraint.java:
New files. These correspond to the C types MR_TypeClassId,
MR_TypeClassMethod, MR_TypeClassDeclStruct,
and MR_TypeClassConstraint in the C runtime.
java/runtime/TypeCtorInfo_Struct.java:
Add a comment.
compiler/rtti_to_mlds.m:
Don't cast null pointers to mlds__generic_type; they should have
the right type already. Casting to mlds__generic_type here causes
type errors for the Java back-end, because in Java there are no
implicit conversions from Object (unlike C, which allows implicit
conversions from `void *').
compiler/rtti.m:
Change tc_rtti_name_java_type so that it maps the new typeclass-related
RTTI types to the appropriate Java types.
library/private_builtin.m:
Define MR_PREDICATE and MR_FUNCTION.
java/runtime/PredFunc.java:
Fix a bug in my previous change:
s/MR_PRED/MR_PREDICATE/
s/MR_FUNC/MR_FUNCTION/
