x264-devel: update to 20161023

Approximate changelog:

Remove misaligned SSE support; could cause problems if exception masks
were messed with by libraries and is obsoleted by AVX.
Fix AVX2 detection if "limit CPUID" is enabled in the BIOS.
Fix cases where intra refresh could predict from disallowed pixels.
x86inc: support "x64"-marked Windows 64-bit machines.
Improvements:
Support cygwin 64-bit.
x86: faster SAD_X3/SAD_X4
Transparent hugepage support and optimization on Linux.
AVC-Intra encoding support.
Windows Unicode (UTF-16) support.
Fix compilation with OpenCL on OS X.
Fix a crash in the case of an OpenCL error during encoding with OpenCL.
Fix building in compilers without inline asm support.
Fix crash in high bit depth builds compiled with unaligned stack.
Fix potential misalignment crash in AVX2 denoise_dct.
Fix some builds with PIC.
Fix possible crash when writing very large filler NALUs.
Improvements:
Add --stitchable option for segmented encoding.
Add new color primaries, transfer characteristics, and matrix
coefficient options from the latest H.264 spec.
x86: optimizations to AVX2 iDCT and AVX deblock
Tweak i16x16 delta-quant-avoidance code to fix a rare flickering issue
with deblocking in static areas of the frame.
Fix an invalid memcpy in sliced-threads that sometimes used src==dst;
this probably didn't break anything, but valgrind complains and it's
technically wrong.
Fix a stack alignment bug in checkasm and use 64-bit cycle counters to
avoid overflows that could occur in some tests.
x86inc: Remove .rodata kludges; they're no longer necessary and could
cause other problems.
Improvements:
x86: add Jaguar CPU detection.
x86inc: utilize the shadow space on win64 to avoid stack pointer
manipulation in some functions.
x86: 32-byte align the stack if possible, avoiding explicit alignment
routines in ALIGNED_ARRAY for AVX2-aligned arrays.
x86: Various optimizations and a bunch of new AVX2 functions,
especially for high bit depth.
OpenCL refactoring: autoload the OpenCL library, clean up the code,
and increment X264_BUILD.

Log message:
x264-devel: if we don't pass the assembly test, e.g. if we don't
pass optimizing flags (like default netbsd setup), just act as if
we passed --disable-asm, as opposed to passing it for netbsd/arm.

- now other operating systems that don't optimize won't fail here.
- if someone does pass optimization, he benefits from it
- I don't have to define another case in the Makefile for MIPS
