Parallelized LLVM invocation. The number of threads to use can be specified in
the Config and on the command line. If more than 1 thread is used the LLVM
stuff will be done in separate threads. If a single thread is used everything
will run in the same thread just as before. (#405)
Slightly decreased memory usage in the ClassCompiler. Don't generate a large
String from the Module and then write to the Writer but rather just write the
Module directly. (#406)
Refactored things a bit after parallelizing the LLVM invocation in order to
make it easier to use from the Eclipse plugin. (#405)
