cpuminer v1.4: x64 Opts

• X64 optimizations, about 10% on most hardware, more on others.
• Added --cpu-affinity-oneway-mask for masking cpus on oneways.
• Compiled under GCC 7.2 (with NEON support for armv7).

Installation instructions:

Note: for some reason O2 is faster for x64 and armv8, but O3 is faster for armv7.

Armv8, Hugepages, oneways

Compiled under GCC 7.2 (with NEON support for armv7).

Hugepage support, and forcing oneway support are enabled.
