Adding function build_inter_predictors_for_planes to build inter
predictors for specified planes. This function allows to remove
condition "#if CONFIG_ALPHA" and use MAX_MB_PLANE for general case.
Renaming 'which_mv' local var to 'ref', and 'weight' argument to 'ref'.

Invert loops to operate vertically in the inner loop. This allows
removing redundant loads.
Also add preloading of data.

Each iteration of the horizontal loop reuses 7 of the 11 source
values. Loading only the 4 new values saves some time.
Also add preload for source data.
Overall 4% faster on Chromebook.

'skippable' can remain unset and negatively affect later decisions

Loop filter configuration doesn't belong to macroblock, so moving it from
MACROBLOCKD to VP9_COMMON. Also moving the declaration of loopfilter struct
from vp9_blockd.h to vp9_loopfilter.h.

The memset sets 16 bytes rather than the correct size of the
final array dimension (MAX_MODE_LF_DELTAS).
(In response to bug posted by Manjit Hota to codec-devel
and webm-discuss lists)

The mix use of double type and simd code caused invalid values stored
in double variables, further caused unit tests to fail. The failures
were only observed on x86-win32-vs9 build with vs2008.

Adds a new subpel motion estimation function that uses a 2-level
tree-structured decision tree to eliminate redundant computations.
It searches fewer points than iterative search (which can search
the same point multiple times) but has the same quality roughly.
This is made the default setting at speeds 0 and 1, while at
speed 2 and above only a 1-level search is used.
Also includes various cleanups for consistency and redundancy removal.
Results:
derf: +0.012% psnr
stdhd: +0.09% psnr
Speedup of about 2-3%

Different partitionings were not being evaluated against
best_rd and there were unnecessary calls to RDCOST. This
could have resulted in a non-optimal partioning being
selected.
I simplified the variables used to track the rate,
distortion and RD values throughout the function.

Using block width and block height instead of their logarithms. Using
SUBPEL_BITS and SUBPEL_SHIFTS constants instead of magic numbers.
