x86: move XOP emulation code back to x86inc
Only two functions that use xop multiply-accumulate instructions where the first operand is the same as the fourth actually took advantage of the macros. This further reduces differences with x264's x86inc. Reviewed-by: Ronald S. Bultje <rsbultje@gmail.com> Signed-off-by: James Almer <jamrial@gmail.com> |

swr: rewrite resample_common/linear_float_sse/avx in yasm.
Linear interpolation goes from 63 (llvm) or 58 (gcc) to 48 (yasm) cycles/sample on 64bit, or from 66 (llvm/gcc) to 52 (yasm) cycles/ sample on 32bit. Bon-linear goes from 43 (llvm) or 38 (gcc) to 32 (yasm) cycles/sample on 64bit, or from 46 (llvm) or 44 (gcc) to 38 (yasm) cycles/sample on 32bit (all testing on OSX 10.9.2, llvm 5.1 and gcc 4.8/9).
