Use precise context to estimate coeff rate cost
Use the precise context to estimate the zero token cost in trellis
optimization process. This improves the speed 0 coding performance
by 0.15% for lowres and 0.1% for midres. It improves the speed 1
coding performance by 0.2% for midres and hdres.

Enable uniform quantization with trellis optimization in speed 0

Refactor coeff_cost() function
Move the operations that update the context buffers outside this
function. The coeff_cost() takes all input as const value and returns
the coefficient cost.
This makes preparation for the next coefficient optimization CLs.

Remove txfrm_block_to_raster_xy() from vp9 encoder
The transform block row and column positions are always available

Fix error in get_ul_intra_threshold() for 10/12 bit.
The scaling of the threshold for 10 and 12 bit here appears
to be in the wrong direction. For 10 and 12 bit we expect sse
values to be higher and hence the threshold used should be
scaled up not down.

quantization, to avoid quality regression in some conditions.

For forced key frames in particular this helps to make them
