elf: tst-audit10: split AVX512F code into dedicated functions [BZ #32882]release/2.41/master
"Recent" GCC versions (since commit fc62716fe8d1, backported to stable
branches) emit a vzeroupper instruction at the end of functions
containing AVX instructions. This causes the tst-audit10 test to fail
on CPUs lacking AVX instructions, despite the AVX512F check. The crash
occurs in the pltenter function of tst-auditmod10b.c.
Fix that by moving the code guarded by the check_avx512 function into
specific functions using the target ("avx512f") attribute. Note that
since commit 5359c3bc91cc ("x86-64: Remove compiler -mavx512f check") it
is safe to assume that the compiler has AVX512F support, thus the
__AVX512F__ checks can be dropped.
Tested on non-AVX, AVX2 and AVX512F machines.
