Justin Ruggles acd9948e74 lavr: x86: fix ff_conv_fltp_to_flt_6ch function prototypes 
Changed to match the number of parameters in conv_func_interleave(), which is
how they are called. The change isn't strictly necessary because the 4th
parameter is not used, but the code is clearer if they match.

Justin Ruggles 5cc6d5244d lavr: replace the SSE version of ff_conv_fltp_to_flt_6ch() with SSE4 and AVX 
The current SSE version is slower than the MMX version on Athlon64 and Sandy
Bridge, but the SSE4 and AVX versions are faster on Sandy Bridge.
