81452cf0b7 Refactor intra block prediction function
This commit simplifies the intra block boundary condition logic.
It removes the block index from the argument set.

9b4f9f45ee Fill buffer speed up
Eliminates the byte by byte read from bool decoder,  by reading
in a size_t and then shifting it into place.

13a4f14710 Eliminate num_8x8 and num_4x4 width/height lookups
Also some log2 lookups.

Pass in 8x8 block width/height and log2 num4x4s instead.

8783a8a97c Refactor transform block loop for inter mode decoding
Rework the inter mode transform block decoding loop. Replace the
block index with the row and col index as the input argument. It
saves function call to compute the row and col index according to
the block index and overall block size, and many if statements
associated with the transform block position relative to the coding
block. For the test bit-stream pedestrian_area 1080p at 5 Mbps,
the decoding speed goes up from 81.13 fps to 81.92 fps.

Note that the intra coded block decoding needs more refactoring
work than the inter ones. So keep it using foreach_transforme_block
as for now.

89090d8046 Don't allocate dqcoeff in MACROBLOCKD.
The encoder gets its dqcoeff from the context tree. In the decoder move
it to directly after MACROBLOCKD.

7e0d0de211 Refactor inverse_transform_block argument list
Replace block index with transform type in the argument list. This
allows to save an extra fetch to the prediction mode. For pedestrian
area 1080p coded at 5 Mbps with single tile, the average decoding
speed goes up from 80.55 fps (before the refactoring series) to
81.13 fps.

cccad1c5de Reduce dqcoeff array size in decoder
The decoding process handles detokenization and reconstruction per
transform block sequentially. There is no need to offset the dqcoeff
buffer according to the transform block index. This allows to
reduce the memory spill and improve cache performance.
