This is a cosmetic patch that removes a great deal of conditional
compilation around CONFIG_VAR_TX from the partition search function.

In preparation for adding more 1D variants with ADST/FlipADST/etc.

BDRATE actually improves by 0.21% on lowres.

Change-Id: I2fa4720c69fe001fa666119a284dfc6b17fffab2

Optimized 2 up-sampled reference prediction functions in high-bit
depth case. This reduced the HBD encoding time by 3%.

Instead of testing all interpfilter-BMC/OBMC combinations, we choose
the best interpolation filter based on regular inter prediction.

Reduction in encoding time: ~10%
Drop in performance gain: 0.08% lowres, 0.04% midres

Change-Id: Ifc19097a918ac76b529db9af4c60e2c70e93f7ad

Temporarily disable transform type selection for 32x32 transform
block size. This speeds up the encoding process. For bus at CIF
150 frames, the encoding time goes from 896s -> 762s (11% faster).
The compression performance for lowres set is improved by 0.15%,
and -0.029% for hdres.

Change-Id: If239b272970eb302150bec13b8cf192fbe045332

Using the up-sampled reference frames in sub-pixel motion search is
enabled as a speed feature for good-quality mode speed 0 and speed 1.
