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...

x86: use raw opcode for xgetbv instruction

This allows the CPU detection to work with assemblers not supporting
the xgetbv mnemonic. These include clang and some BSD versions.

All AVX code will be written for yasm, where the main assembler
is not involved....

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.
