Fix broken tests for avr target

These tests assume {unsigned,} ints are 32 bits or wider. Explicitly
specify __{U}INT32_TYPE__ for targets with __SIZEOF_INT__ < 4.

	* 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.
