Broken SH2a patches

Thanks - I have put that into the latest patch (attached) along with a 
fix for the other problem you spotted 
(arch_sh2a_nofpu_or_sh4_nommu_nofpu being the same as 
arch_sh2a_nofpu_or_sh3_nommu).  Otherwise this patch is the same as the 
previous one with a suitably amended arch_expected.txt for the GAS tests.

Personally yes - but only if:

   a) Someone is willing to put the effort into developing it.  I do not 
think that it will be a trivial programming exercise and I am not 
volunteering, at least not right now.

   b) There are more SH variants to come.  A bit of crystal ball gazing 
is required for this one, but presumably it is quite likely that the SH 
line will continue to be developed.

Cheers
   Nick
