 The problem is that expand_divmod generates a zero extension of a
 constant, which is VOIDmode:
 
 (insn 11 10 12
       (nil)
       (set (reg:DI 72)
 	   (truncate:DI (lshiftrt:TI (mult:TI (zero_extend:TI (reg/v:DI 70 [time]))
 					      (zero_extend:TI (const_int 65 [0x41])))
 				     (const_int 64 [0x40])))) -1 (nil)
 				     (nil))
 
 Should expand_divmod not generate this, or should
 simplify_unary_operation be able to handle it?
