/* This testcase failed on i686 because (const_int -1) was changed into
   (const_int 0xffff) when storing it into SImode pseudo, but was not
   converted back to (const_int -1) when returning from store_expr,
   even though target was (subreg:HI (reg/v:SI indx)).  But (const_int 0xffff)
   is not valid general_operand in HImode.  */
