    Skip sloppy PR121035 test

    gcc.dg/pr121035.c failed with

    FAIL: gcc.dg/pr121035.c (test for excess errors)
    Excess errors:
    gcc.dg/pr121035.c:92:1: error: incompatible types in 'PHI' argument 1
    unsigned int
    long unsigned int
    _11 = PHI <0(5), 4294967295(6)>
    gcc.dg/pr121035.c:92:1: error: type mismatch in binary expression
    unsigned int
    unsigned int
    long unsigned int
    _6 = g_15 * 4294967294;

    so the test case assumes int32plus at the least, changed accordingly.

            PR testsuite/121035
            * gcc.dg/pr121035.c: Require int32plus.
