David Marchand	b366fa2f49	dpif-netdev: Call cpuid for x86 isa availability. ... DPIF AVX512 optimizations currently rely on DPDK availability while they can be used without DPDK. Besides, checking for availability of some isa only has to be done once and won't change while a OVS process runs. Resolve isa availability in constructors by using a simplified query based on cpuid API that comes from the compiler. Note: this also fixes the check on BMI2 availability: DPDK had a bug for this isa, see https://git.dpdk.org/dpdk/commit/?id=aae3037ab1e0.
