This facilitates "universal" builds, ones that target multiple
architectures, e.g. ARMv5 through ARMv7. See commentary in
Configure for details.

Fix SEH and stack handling in Win64 build.

Pointer out and suggested by: Ard Biesheuvel.

- fix 32-bit build (submitted by Ard Biesheuvel);
- fix performance issue in CTR;

Submitted by: Ard Biesheuvel.

10-19% improvement depending on key length and endianness.

"Teaser" means that it's initial proof-of-concept to build EVP module
upon.

"Teaser" means that it's not integrated yet and purpose of this
commit is primarily informational, to exhibit design choices,
such as how to handle alignment and endianness. In other words
it's proof-of-concept code that EVP module will build upon.

Improve CBC decrypt and CTR by ~13/16%, which adds up to ~25/33%
improvement over "pre-Silvermont" version. [Add performance table to
aesni-x86.pl].

Atom Silvermont. On other CPUs one can observe 1% loss on some
algorithms.
