Fixed a crasher where entering 'help disasm' on the command line would crash lldb.
The reasom of the crash is because of a missing entry in the argument table corresponding to eArgTypeUnsignedInteger.
Add such entry and modify the call site of the crash to go through a fail-fast API to retrieve the argument table.
Add a regression test to TestHelp.py.
