this allows disabling and enabling it
it also prevents crashes if vfpv3 and neon are disabled which previously
would have enabled the flag

And last but not least one can enable setend on cpus like cortex-a8 where
its fast but disabled by default

Errors go to stderr, but the cpu stats are non error output for cputest

This fixes echoing the cpu test results

Add CPU count and number threads as informative values for fate.

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.

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.

It will be useful in lavfi, and could conceivably be useful to the user
applications as well.

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.
