Avoid printing absolute addresses in oatdump
- Added printing of OatClass offsets.
- Added printing of OatMethod offsets.
- Added bounds checks for code size size, code size, mapping table, gc map, vmap table.
- Added sanity check of 100k for code size.
- Added partial disassembly of questionable code.
- Added --no-disassemble to disable disassembly.
- Added --no-dump:vmap to disable vmap dumping.
- Reordered OatMethod info to be in file order.
