This test fails consistently on the new valkyrie autobuilder cluster

The estimate instructions (rcpss, rcpps, rsqrtps, rsqrtss) are, as the
name suggests, not expected to give a fully accurate result. They may
produce slighly different results on different CPU families because
their results are not defined by the IEEE standard.
