OK, so that is not it.
The problem is that can_assign_to_reg_p() returns true when x is
(ashift:HI (reg/v:HI 27 [ n ]) (subreg:QI (reg/v:HI 27 [ n ]) 0)).
num_clobbers == 1 but added_clobbers_hard_reg_p returns false.
It seems to me that store motion is OK here, but I don't know who is
usually responsible for adding the clobbers...
