This patch adds avx512 support for xbzrle_encode_buffer function to accelerate xbzrle encoding speed.
The specific avx512 implementation is provided in qemu/migration/xbzrle.c.
We provide AVX512 intrinsic support in qemu/configure file to enable avx512 in complier.
And added unit test called "test_encode_decode_random" is provided in qemu/tests/u nits/test-xbzrle.c.
