Prefer SSE4.1 implementation of SAD over AVX2
...
It seems that the 128-bit wide version consistently outperforms the
256-bit one

Use SSE instead of AVX for small widths

Highly dubious if this will help performance at all

Optimize SSE4.1 version of SAD
...
Make it use the same vblend trick as AVX2. Interestingly, on my test
setup this seems to be faster than the same code using 256-bit AVX
vectors.

Modify AVX2 SAD to mask data by byte granularity in AVX registers

Avoids using any SAD calculations narrower than 256 bits, and
simplifies the code. Also improves execution speed

x86 asm: mark stack as non-executable
...
Gentoo's `scanelf` QA tool detects writable/executable stack
of assembly-writtent files as:
```
$ scanelf -qRa .
0644 LE !WX --- --- ./src/strategies/x86_asm/.libs/picture-x86-asm-sad.o
0644 LE !WX --- --- ./src/strategies/x86_asm/.libs/picture-x86-asm-satd.o
0644 LE !WX --- --- ./src/strategies/x86_asm/picture-x86-asm-sad.o
0644 LE !WX --- --- ./src/strategies/x86_asm/picture-x86-asm-satd.o
```
Normally C compiler emits non-executable stack marking (or GNU assembler
via `-Wa,--noexecstack`).
The change adds non-executable stack marking for yasm-based assmbly files.
https://wiki.gentoo.org/wiki/Hardened/GNU_stack_quickstart has more details.

Require BMI and ABM instruction sets for AVX2 build
...
AVX2 support on a processor should always imply BMI and ABM support.
The lzcnt and tzcnt instructions have more suitable semantics in the
corner case that source word is 0, and allow us to even handle that
scenario without a branch. Apparently Visual Studio will already
include this support when building with AVX2 enabled, so only the
automake files need to be tweaked.
