Update tst-gnu2-tls2 tests to set XMM0...XMM7 to all 1s in malloc to verify that XMM registers are preserved when _dl_tlsdesc_dynamic is called by clearing vectors with zeroed XMM registers before _dl_tlsdesc_dynamic and using these XMM registers to clear vectors after _dl_tlsdesc_dynamic. This improves the BZ #31372 test. Signed-off-by: H.J. Lu <hjl.tools@gmail.com> Reviewed-by: Sam James <sam@gentoo.org>
