Subject: Let YUV plane share the same dqcoeff buffer.
X-Git-Tag: v1.4.0~331
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=b7166143d0137518b98353062c8dc73b9e2904d7;p=libvpx

Let YUV plane share the same dqcoeff buffer.

Remove unnecessary dqcoeff from macroblockd which reduce macroblockd
size by 16384 bytes.
