2b43a1ee18 Clean 32x32 full idct sse2 and ssse3 code 
vpx_idct32x32_1024_add_ssse3() is actually a sse2 function and faster
than vpx_idct32x32_1024_add_sse2(). Replace the slow one. All are
code relocations, no new code.

08a453b9de Replace vp9_ prefix with vpx_ prefix in vpx_dsp function names 
This commit clears the function naming convention in vpx_dsp. It
replaces vp9_ prefix of global functions with vpx_ prefix. It also
removes the vp9_ prefix from static functions.
