    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
