Build datetime for Windows. However, to make this compile faster need to make cl.exe build each file at a time, otherwise every incremental build starts from scratch.

Made chunk sizes a run-time option rather than a compile-time option. However, I have not yet instituted checks for CPU incompatibility. Right now if you run this on a machine that does not support AVX, it may crash with illegal instructions.

This is a major revision 1.1. X-Mem now builds and runs on both Windows and GNU/Linux. The results I am getting on Linux for 256-bit sequential multithreaded reads is suspect, however.

Disabled USE_LARGE_PAGES support for GNU/Linux for now, for two reasons. First, I use libhugetlbfs since Linux does not have very good support for large pages, but this library does not expose NUMA-aware functionality. Second, I get segmentation faults if I try to use ThroughputBenchmark on anything larger than a single large page. I also removed g++ flags for AVX2 instruction set, which was causing the code not to run on my Ivy Bridge machine (obviously, since AVX2 is Haswell and newer only). Fortunately, I am not needing any AVX2 instructions to do 256-bit memory operations so this is OK for now.

Implemented large/huge pages for GNU/Linux build. However, it appears that libhugetlbfs and hugetlbfs in general is not NUMA-aware...so currently the benchmark memory allocations with USE_LARGE_PAGES on Linux are not guaranteed to use NUMA correctly. This is not an issue on single-node systems, however. Also fixed a bug with converting CPU numbers in a NUMA node using libnuma that was causing segmentation faults.

Finished superficially porting X-Mem to Linux. It compiles and links correctly now but segfaults when you attempt to run a benchmark. There are definitely some things that I avoid porting, such as querying generic system information in the beginning. I also will need to disassemble compiled benchmarks and see what happens.

Further porting work to Unix. Unfortunately, it does not look like NUMA+large pages will be possible on Linux.. need to investigate this further. If this is in fact the case, Linux performance may suffer compared to Windows.
