I would skip the SBDwarf.h and just make a simple DWARF opcode parser all in python. We only need it to handle the opcodes that are currently used by any supported targets. Since this is for testing we shouldn't add something to the public API unless it is going to be used by clients of the LLDB library. So I would port your SBDwarf.h to python:

  DW_OP_addr                          = 0x03

You are already writing a manual opcode parser so adding a few defines ins't a big deal. You might want to create a new lldbdwarf.py file that contains DWARF stuff to keep things clean. You can also make the DWARF expression evaluator live in that new file.
