    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.
