testsuite: Fixes for test case pr117546.c

This test fails on AVR.

Debugging the test on x86 host, I noticed that u in function s sometimes
has value 16128.  The "t <= 3 * u" expression in the same function
results in signed integer overflow for targets with sizeof(int)=2.

Fix by requiring int32 effective target.

Also add return statement for the main function.

gcc/testsuite/ChangeLog:

	* gcc.dg/torture/pr117546.c: Require effective target int32.
	(main): Add return statement.
