* -XX:TraceC1X=0...5 controls the native c1x tracing
* -Dc1x.debug=true turns on the logging proxies and lots of log output on the java side
* provide more information about types to the compiler (type hierarchy, etc)
* 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)
* unresolved methods
* class resolving - class patching (asssembly prototype copying)
