[PATCH v2 1/1] testsuite: prevent packing enum in vect-early-break_65.c [PR124112]

[Torbjörn Svensson via Sourceware Forge]

From: Torbjörn SVENSSON <torbjorn.svens...@foss.st.com>

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.

        * gcc.dg/vect/vect-early-break_65.c: Prevent packing enum to a
        smaller object.
