re PR middle-end/78416 (wrong code for division by (u128)~INT64_MAX at -O0)

PR middle-end/78416
* expmed.c (expand_divmod): Use wide_int for computation of
op1_is_pow2.  Don't set it if op1 is 0.  Formatting fixes.
Use size <= HOST_BITS_PER_WIDE_INT instead of
HOST_BITS_PER_WIDE_INT >= size.

* gcc.dg/torture/pr78416.c: New test.
