conf: add new machine intel-skylake-64
Add 64-bit new machine (intel-skylake-64) with -march=skylake and avx2 instruction-set set up. We do see a qemu-usermode failure at build time, on setup of avx2 instruction-set as QEMU does not support AVX instruction set. Check this: https://bugs.launchpad.net/qemu/+bug/1818075 So to bypass this issue disabling qemu-usermode for intel-skylake-64 machine. Due to above limitation and in order to not affecting existing machines, this new machine is being proposed to add. A quick performance comparision between intel-corei7-64 vs intel-skylake-64 machines Measurements are in time, taken by the benchmark tests. Less is better.

4#@DESCRIPTION: Machine configuration for 64 bit Intel Skylake CPU (and later) with MMX, SSE, SSE2, SSE3, SSE4.1, SSE4.2, AVX, and AVX2 instruction set support. Supports a moderately wide range of drivers that should boot and be usable on "typical" hardware.
