Broken SH2a patches

[Nick Clifton]

Hi Andrew,

Sorry that this is later than advertised...

Ok, here is a patch that I think fixes up the diagram and removes the 
|'s from the opcodes table.  What do you think ?

It is intended for the assembler and disassembler.  It has no affect on 
architecture selection.
