* provide exception handler tables to the compiler
* add exception handlers to the nmethod
* correct implementation of ExceptionObject
* exception handling/unwinding entry points
* modified versions of handle/unwind exception stubs using standard calling conventions
* exception throwing
* implicit null pointer exception, implicit div by 0 exception
* arraystore/classcast/arrayindex exceptions
* checkcast implementation
* newarray, anewarray, multinewarray implementation
* correct new instance initialization
* access to java class mirrors (for ldc)
