    testsuite: prevent packing enum in vect-early-break_65.c [PR124112]

    GCC might be compiled with -fshort-enum enabled by default.
    For those targets, it is important that the enum type is not packed into
    something smaller than int, or vectorization will not match.

            smaller object.
