Detect and check for CMOV.
...
Some MMX-only CPUs do not have support for CMOV.
All SSE/MMX2 CPUs should be fine, thus no check was
added to those functions.

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.

Clean up av_get_cpu_flag()
...
Instead of defining functions in per-arch header files included
by the main cpu.c, define them normally and call them from the
generic one.
