Temporary tweak to reinstate a change that disappeared when sse2.cc was removed.

Browse Source 
The 64 bit variant of MOVNTI was not decoded.  The proper fix for this is to work on
fetchdecode64.cc to call a 64 bit variant of SSE instructions or fail it with a
invalid op.  A careful check needs to be done with the AMD manuals to determine if
there are any other SSE instructions that have a special 64 bit decoding.
