Fixed some issues, extended test suite:

1. For some reason lookupTarget function didn't link on MacOS x,
   I have no idea why, so I've just reimplemented it manually.

2. Removed insn suboperand

3. The number of operands is no longer a constant (ARM can have lots of
   operands)

4. readbin now will sweep all data sections in addition to symbols.

5. extended test suite with running readbin on arm binaries and on itself.
