[Patch, testsuite] Fix more failing tests for avr

[Senthil Kumar Selvaraj]

Hi,

  The below trivial patch fixes some more testsuite failures for the avr
  target. They fail for avr because they assume ints are 32 bits or
  wider. The patch uses explicit __{U}INT32_TYPE__ for targets with
  smaller int size.

  Committed as obvious.

Regards
Senthil

        * gcc.c-torture/execute/pr79121.c:Use __{U}INT32_TYPE__ for targets
        with sizeof(int) < 4.
        * gcc.c-torture/execute/pr79737-1.c (struct S): Likewise.
        * gcc.c-torture/execute/pr79737-2.c: Likewise.
        * gcc.dg/torture/pr79777.c: Likewise.
        * gcc.dg/torture/pr79910.c: Likewise.
