      update arm idct functions · 56f5a9a0
      Johann authored
      Jeff Muizelaar posted some changes to the idct/reconstruction c code.
      This is the equivalent update for the arm assembly.
      
      This shows a good boost on v6, and a minor boost on neon.
      Here are some numbers for highway in qcif, 2641 frames:
      HEAD neon: ~161 fps
      new neon:  ~162 fps
      HEAD v6:   ~102 fps
      new v6:    ~106 fps
      
      The following functions have been updated for armv6 and neon:
      vp8_dc_only_idct_add
      vp8_dequant_idct_add
      vp8_dequant_dc_idct_add
      
      Conflicts:
      
      	vp8/decoder/arm/armv6/dequantdcidct_v6.asm
      	vp8/decoder/arm/armv6/dequantidct_v6.asm
      
      Resolved by removing these files. When I rewrote the functions, I also
      moved the files to dequant_dc_idct_v6.asm/dequant_idct_v6.asm
