Some fixes to the Java back-end to make it support RTTI
better. The aim is to at least be able to *compile* code
that makes use of polymorphism (e.g. the Mercury standard
library!), although that aim is not yet achieved with this diff.
Getting code which actually *uses* the RTTI to work is still
a long way off...
compiler/rtti.m:
compiler/mlds_to_java.m:
Fix some bugs in the code to output RTTI type names.
compiler/mlds_to_java.m:
Output the RTTI definitions. This is needed to avoid errors
in code which references them.
Handle initializers better; in particular deal with nested
initializers properly.
Pass the current module name down to output_lval, so that we can
module-qualify data names only if they occur in a different
module. This is needed to ensure that static data defined
in other modules gets module-qualified, but local variables don't.
This also required change some places which were incorrectly
calling output_fully_qualified_name to instead call output_name.
Add comments in the generated output code when generating
"java.lang.Object", so that it is clearer what kind of object
is involved.
Add some special treatment for the types with hand-defined RTTI.
java/runtime/*.java:
Add some definitions of RTTI types, and some new constructors
for the RTTI types that were already defined.
These are currently all just stubs.

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.

mercury/java/Makefile:
A simple Makefile to set up a couple of symbolic links so we can
just include the mercury/java directory in our CLASSPATH.

These are partial Java versions of mercury library modules. They are
very rough but will currently allow for most of the tests/benchmark
directory to run in Java.
