Silence unused parameter warnings.

The various motion search functions share a
common function prototype. In the case of
vp9_full_range_search() two of the parameters
are not needed.

AVX2 To VP9 Block Error Optimization

vp9_block_error_sse2 can only handle 16 bytes at a time but
the function requires to handle a sequence of 32 bytes at a time
so each 16 bytes is handled in a different register.
With AVX2 optimization the 32 bytes can be handled in one register instead
of two in the SSE2
The vp9_block_error was optimized by 85%.
The user level was optimized by 1.2%

Failed 

This patch did not address all the assembly issues 
some of the vp8 assembly counts on 5 arguments being passed in to this function:   

one example : vp8_sad8x16_wmt

Please address or split this into vp9 and vp8 patches.
