x86: Test wcscmp RTM in the wcsncmp overflow case [BZ #28896]
In the overflow fallback strncmp-avx2-rtm and wcsncmp-avx2-rtm would call strcmp-avx2 and wcscmp-avx2 respectively. This would have not checks around vzeroupper and would trigger spurious aborts. This commit fixes that. test-strcmp, test-strncmp, test-wcscmp, and test-wcsncmp all pass on AVX2 machines with and without RTM. Reviewed-by: H.J. Lu <hjl.tools@gmail.com>
