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()
...

by the main cpu.c, define them normally and call them from the
generic one.
