      3 (hi) Add gc card marking to aput/iput/sput/new_filled_array
      4 (hi) Correct stack overflow handling (dvmCleanupStackOverflow takes an
      5      additional argument now)
      6 (hi) WITH_DEBUGGER and WITH_PROFILER are no longer defined (but are
      7      assumed to be enabled)
      8 (hi) Implement OP_DISPATCH_FF for real. (Right now it's treated as
      9      an unused instruction.)
     10 (hi) Rename dvmJitGetCodeAddr to dvmJitGetTraceAddr.
     11 (hi) Remove references to rGLUE and replace with rSELF
     12 (hi) Rework interpreter to co-exist the new switching model which
     13      elminiates a separate debug interpreter.  Needs a dedicated
     14      rIBASE register (or alternate switching model with variable
     15      handler base).
     16 (hi) Add dvmReportXXXX()" calls in footer.cpp to support profilers &
     17      debuggers.
     18 (hi) Set self->debugIsMethodEntry in invoke code.

     20 (md) Add implementations for jumbo opcodes (40 instructions) and
     21      their volatile variants (13 instructions)
     22 (md) Correct OP_MONITOR_EXIT (need to adjust PC before throw)
     23 (md) OP_THROW needs to export the PC
     24 (md) Use dvmThrowArrayIndexOutOfBoundsException(length, index) for
     25      array bounds errors.
     26 (md) Use dvmThrowClassCastException(actual, desired) for class cast errors.
     27 (md) Use dvmThrowArrayStoreExceptionIncompatibleElement(actual, desired)
     28      for array store errors.
     29 (md) Use dvmThrowNegativeArraySizeException(len) forarray alloc errors
     30 (md) Replace any remaining use of dvmThrowException with proper helper function

     32 (lo) Implement OP_BREAKPOINT
     33 (lo) Implement OP_*_VOLATILE (12 instructions)
     34 (lo) Implement OP_RETURN_VOID_BARRIER
     35 (lo) Implement OP_INVOKE_OBJECT_INIT
     36 (lo) Implement dvmJitScanAllClassPointers
