E2K: added support for MCST Elbrus 2000 CPU architecture
e2k (Elbrus 2000) - this is a VLIW/EPIC architecture, the like Intel Itanium (IA-64) architecture. The architecture has half native / half software support for most Intel/AMD SIMD (e.g. MMX/SSE/SSE2/SSE3/SSSE3/SSE4.1/SSE4.2/AES/AVX/AVX2 & 3DNow!/SSE4a/XOP/FMA4) via intrinsics. https://en.wikipedia.org/wiki/Elbrus_2000 closes https://github.com/official-stockfish/Stockfish/pull/3425 No functional changepull/3460/head
