The patch Mikael references removes some bogus code which prevents
simplification of a subreg of the frame pointer which was causing some problems
for the ARM. This case (x86) shows the same failing behaviour, we have a
subreg of the frame pointer which triggers a reload we're ultimately unable to
handle.
I'm going to go ahead and mark this as resolved since I believe Bernd nailed it
which is reinforced by Mikael's comments that backporting that fix to the 4.5
and 4.4 branches fixes the problem on the branches as well.
