Implement RTTI for the Java-backend (incomplete)
java/runtime/PseudoTypeInfo.java:
java/runtime/TypeCtorInfo_Struct.java:
java/runtime/TypeInfo_Struct.java:
Implement the `unify' operation for these classes. This implementation
actually just compares them.
library/rtti_implementation.m:
Document a bug in notag_functor_arg_type/1
Define the foreign type of `type_layout' as `TypeLayout' in Java.
Correct an off-by-one error in type_ctor_and_args/3.
Implement deconstruct/8 for TypeCtorRep = enum.
Implement the following predicates in Java:
get_var_arity_typeinfo_arity/1
get_pti_from_arg_types/2
typeinfo_is_variable/2
get_type_ctor_info/1
get_primary_tag/1
get_remote_secondary_tag/1

library/type_desc.m:
Implement the following procedures for Java:
type_of/1
has_type/1
type_ctor_and_args/3
type_ctor_name_and_arity/4
Implement the Java classes `type_desc_0' and `type_ctor_desc_0'.

Bug fixes and code simplifications in the RTTI handling
for the Java back-end.
compiler/rtti.m:
For Java, map all the different C representations for TypeInfos
to a single Java type "java.runtime.TypeInfo_Struct".
Likewise map all the different C representations for type class
constraints to a single Java type "java.runtime.TypeInfo_Struct".

java/runtime/VA_PseudoTypeInfo_Struct4.java:
java/runtime/VA_PseudoTypeInfo_Struct8.java:
java/runtime/TypeclassInfo.java:
Deleted these stub files, since they should no longer be needed.
java/runtime/TypeInfo_Struct.java:
Add two new constructors, corresponding to the constructors for
the deleted FA_* and VA_*.java files.
java/runtime/PseudoTypeInfo.java:
Add some comments. Make the nullary constructor protected,
to ensure that it is only used by derived classes, since it
is only intended to be used for TypeInfo_Struct.

Runtime fixes for the Java back-end.
java/runtime/DuExistLocn.java:
java/runtime/DuFunctorDesc.java:
java/runtime/DuPtagLayout.java:
Define constructors for these types.
java/runtime/MaybeResAddrFunctorDesc.java:
New file (corresponds to MR_MaybeResAddrFunctorDesc type in C).
java/runtime/MaybeResFunctorDesc.java:
New file (corresponds to MR_MaybeResFunctorDesc type in C).
java/runtime/PseudoTypeInfo.java:
Define constructors.
Make non-abstract (XXX temp work-around only).
java/runtime/TypeCtorInfo_Struct.java:
XXX Pass some parameters of the constructor as "Object",
to work around type errors in invocations of those constructors.
java/runtime/TypeFunctors.java:
java/runtime/TypeLayout.java:
Model the C unions better; use a single field, with accessor
functions that convert to each alternative, not several fields.
java/runtime/TypeclassInfo.java:
Implement as stub (previous code was just copy of TypeInfo.java).
java/runtime/VA_PseudoTypeInfo_Struct*.java:
Fix a bug: change the order of the constructor parameters
to match the way we generate code which invokes those constructors.

This change introduces some (partial) Java versions of the mercury library
which are currently needed to compile some .java files generated by the
mercury compiler for the tests/benchmarks test cases.
These additions are required temporarily for testing purposes until the
mercury library can be compiled in grade java.

very rough but will currently allow for most of the tests/benchmark
directory to run in Java.
