Mans Rullgard f1f792117f 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.

Måns Rullgård 9275438a19 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.
