Cycles: Fix failing avxf cross test on AVX2 cycles_util_avxf_avx2_test failed on the cross test, since it wasn't immediately clear why, the test was disabled. After looking into it, this test when build for AVX2 is generating FMA instructions where the intermediate results have "infinite" precision [1] leading to slightly different results. This diff re-enables the cross test and allows for a small error in the results.
