Fix some potential issues in the pseudo instruction expansion phase: copy implicit operands and memoperands. Also, expand instructions even if their defs are "dead" since they may have implicit kill operands.

 - This provides a convenient alternative to using something llvm::prior or
   manual iterator access, for example::

    if (T *Prev = foo->getPrevNode())
      ...

   instead of::

     iterator it(foo);
     if (it != begin()) {
       --it;
       ... 
     }
