support the undocumented nop mod/rm instructions

[GoogleCodeExporter]

edisassm needs to support the undocumented nop mod/rm instructions. An example 
of one is 0f 19 00 which encodes to nop [eax]. This CAN cause a page fault.

I've looked into this some, and it doesn't seem to be particularly urgent. So 
if there is a demand for it, then I'll update this, otherwise, it will probably 
be left out.

I am considering have a run-time option to enable/disable support for 
disassembly of these ops. We'll see.

edisassm 1.8.1 has support for (at least some of) these undocumented code 
sequences.
