to the dqcoeff or qcoeff buffer. The encoder would populate the dc coeffs of the y blocks as a separate stage (recon_dcblock) and the decoder would use a special version of the idct. This change eliminates the extra copy and reduces the code footprint. [Tero] Added needed changes to armv6 and NEON assembly. Change-Id: I83202ffdbaf83f6e5dd69f4ba2519fcf0b13b3ba
