In h264_deblock_q1, the result of the deblock needs to be kept to
be used in future deblocks, so return this value now.

Also change the sign of tc0 vector: It is really a signed value, so
treat it as such until after the >=0 check;
then, at that point, after being masked, it can be treated as unsigned.

all 255s, and then doing the subtraction, nor of the vector with itself: saves
one instruction and a register.

Let's disable it until we iron this bug out.
