I am currently testing out the attached patch.  I am not sure however if
it is doing the right thing by just silently ignoring DW_CFA_NOPs.  Maybe
it should issue an interpretation along the lines of:

     LOC           CFA      ra      
  0000000000020480 nop      -

What do you think ?

Cheers
  Nick
