This patch provides rte_memcpy* calls optimized for
AMD EPYC platforms. Use config/x86/x86_amd_epyc_linux_gcc
as cross-file with meson to build dpdk for AMD EPYC platforms.  

Please split in 2 patches: platform & memcpy.

What optimization is specific to EPYC?

I dislike the asm code below.
What is AMD specific inside?
Can it use compiler intrinsics as it is done elsewhere?

And why is this not done by Gcc?
