07d8fa5812 fate: add informative cpu test 
libavutil/cpu-test prints raw and effective cpu flags to STDERR. Detected
cpu flags can be useful for debugging fate errors.

No comparison of the result against a expected result since that would
require fate config specific references.

b7b17ed66e aarch64: add cpuflags support for NEON and VFP 
NEON and VFP are currently mandatory for all ARMv8 profiles. Both are
handled as extensions as far as cpuflags are concerned. This is
consistent with handling x86_64 which always has SSE2, but still
handles it as an extension.

2a6eaeaa85 Move get_logical_cpus() from lavc/pthread to lavu/cpu. 
It will be useful in lavfi, and could conceivably be useful to the user
applications as well.

239fdf1b4a x86: build: replace mmx2 by mmxext 
Refactoring mmx2/mmxext YASM code with cpuflags will force renames.
So switching to a consistent naming scheme beforehand is sensible.
The name "mmxext" is more official and widespread and also the name
of the CPU flag, as reported e.g. by the Linux kernel.

eba586b0d9 Add a CPU flag for the Atom processor. 
The Atom has SSSE3 support, which is useful in many cases, but sometimes the
SSSE3 version is slower than the SSE2 equivalent on the Atom, but is generally
faster on other processors supporting SSSE3. This flag allows for selectively
disabling certain SSSE3 functions on the Atom.
