backport Nathan Sidwell's movw fix to 4.4

This ICE was fixed for 4.5 by r148788, Nathan Sidwell's "[ARM] movw fix", see
http://gcc.gnu.org/ml/gcc-patches/2009-06/msg01358.html.

The attached patch backports that fix to current 4.4, which fixes the ICE. 
I've had this in my 4.4 tree since July 2009, so I'm confident it's solid.

Matthias, does this patch work for you?

> Can this patch be submitted to gcc-patches@gcc.gnu.org after due testing ? 

Yes.  Although I've tested this many times it's always been together with many
other patches.  I'm now running a 4.4 bootstrap+regtest with only this one
applied.  Will submit the patch once that succeeds, which should be less than
24 hours from now.
