headline: testsuite: Add AVX512 requirement to a vectorization test.
tldr: The test case vect-early-break-no-epilog_11.c now requires AVX512 instructions on x86_64 to vectorize correctly.

The test case vect-early-break-no-epilog_11.c now requires AVX512 instructions for vectorization on x86_64 architectures. Without AVX512, the test may not vectorize as intended. This change ensures that the test is only run on systems that support AVX512, preventing false negatives.
