SIMD book, update 3! Addition/Subtraction mostly finished

Finally. Apologies for the delay, but it's been a busy month. This time I will hold true to my word and upload a PDF for people to see (attached to this page).

So, what's new? Here is a list of things done:

* Finished ALL addition/subtraction related instructions for all engines and major derivatives (SSE*/AVX, VMX/VSX, NEON/armv8 NEON). With diagrams (these were the reasons it has taken so long).
* Reorganized the structure (split the book into Parts I/II, the instruction index will be in Part II, Part I will carry the design analysis of each SIMD engine.
* Added an TOC/index.
* So far, with just Addition/Subtraction Chapter and the rest empty sections, it has reached 175 pages (B5, again I'm not fixed on the size, it might actually change)! My estimate is that the whole book will surpass 800 pages with everything included.

* Provide actual working examples for all engines/instructions.
* Provide missing implementations of exclusive instructions for the rest of the engines
* Bibliography (I have TONS of items to list, just haven't gotten around it yet).
* Write the rest of the text!

Next update (4) will include:
* Multiplication and perhaps Division as well
