This commit unifies the reference frame control in the rate-
distortion optimization search loop of sub8x8 block size to remove
the control dependency on mode search order.

Improves function to return sad of integer pels by reusing integer
pels already visited in the smallest scale.
Turns on BIGDIA search for speed 4. Also, turns on the
first version of the pruned subpel search at this speed.
derf: -0.32% (speed 4)
Speed seems to improve by at least 5% but subject to verification.

Adds various high bitdepth transform functions and tests.
Much of the changes are related to using typedefs tran_low_t
and tran_high_t for the final transform cofficients and intermediate
stages of the transform computation respectively rather than fixed
types int16_t/int. When vp9_highbitdepth configure flag is off,
these map tp int16_t/int32_t, but when the flag is on, they map
to int32_t/int64_t to make space for needed extra precision.

The variable best_inter_rd is effectively not in use in the rate-
distortion mode search loops of both regular block sizes and sub8x8
block sizes.

The speed feature that skips compound inter prediction modes was
subsumed by other speed features and effectively was not in use.
This commit removes it.

If optimizations use more than one cpu feature, allow
specifying them so that '--disable-X' still works

Integrate intra mode mask speed feature with the mode_skip_mask
scheme. Move it outside the mode search loop in the
vp9_rd_pick_inter_mode_sb function.

This speed feature is used in real-time setting only. Remove the
related condition check in the rate-distortion optimization search
loop.

Refactor overlay frame speed-up related function. Make it unified
with the ref_frame_skip_mask system and Move it out of the mode
search loop.

This commit refactor the rate-distortion optimization search for
regular block sizes to remove the speed feature dependency on mode
search order.

This issue is found when the denoising mode is set to kDenoiserOnYUVAggressive.
Updated the C code to make it the same with SSE version.
I also changed several lines in VP9 denoiser for the code style.

don't bother decoding any further after receiving an earlier decode
error until a key/intra-only frame is encountered.

This commit fixes a bug related to skipping intra mode checking, by
using a separate variable to store the best prediction error from
inter mode. It avoids unintentionally overwriting intra mode
rate-distortion cost, and hence affecting other speed features.

Assigning selected reference frame pointer is done in the
encode_superblock function. No need to do this at the end of
rate-distortion optimization search.
