[testsuite, committed] Require effective target avx512f for tree-prof/pr66295.c

[Tom de Vries]

Hi,

tree-prof/pr66295.c fails for me with:
...
/tmp/ccNQJq0U.s: Assembler messages:
/tmp/ccNQJq0U.s:102: Error: no such instruction: `vpxord %zmm0,%zmm0,%zmm0'
/tmp/ccNQJq0U.s:127: Error: no such instruction: `vpxord %zmm0,%zmm0,%zmm0'
...

The test-case builds clones for the following architectures:
...
__attribute__ ((target_clones("avx,avx2,avx512f,default")));
...

Following the logic in check_effective_target_vect_simd_clones:
...
        # On i?86/x86_64 #pragma omp declare simd builds a sse2, avx,
        # avx2 and avx512f clone.  Only the right clone for the
        # specified arch will be chosen, but still we need to at least
        # be able to assemble avx512f.
        if { (([istarget i?86-*-*] || [istarget x86_64-*-*])
              && [check_effective_target_avx512f]) } {
            set et_vect_simd_clones_saved($et_index) 1
        }
...
we fix the fail by adding a check for effective target avx512f.

Tested on x86_64 with -m64/-m32.

Committed as trivial.

Thanks,
- Tom
