[vector] Exp implementation for Windows

[Lupusoru, Razvan A]

Hi everyone,

Just as with the Linux changes which added .s source files from Intel Short Vector Math Library, I am uploading the initial version for Windows. This includes the .s files for exp along with makefile changes needed to allow building of these files. My colleague Rahul will follow up with the addition of remaining files in a future patch.

Let me know if you have any questions/comments.

Thanks,
Razvan

PS: Rahul has been looking into consolidation of the .s files. I am uploading them as separate files and he will fix it once we have a working technique in places for merging them.
