gcc44-pr38130.patch

I've talked about this with Honza on IRC:
<honza> I would just use "0" constraint. At least in old times with regmove,
regmove was able to discover that it should use same pseudo for input and
output.  If you use pair of "=a" and "a" only reload sees this fact
<honza> so patch is OK with that change.
This is an updated patch which uses "0" instead of "a" constraint for operand
1.
So, can anyone please test it?  Thanks.
