- Implemented Angie's new fwd txfm algorithm.
- Improve ~100% than last 64-bit version; 3 times faster than
original C code.
- Passed bit-exact unit test.

With ext-ref enabled, it is possible that when trying to encode the
first true ALTREF frame after a keyframe, the previous ALTREF frame
(alias for the keyframe) is the same as one of the new LAST{2,3,4}
reference frames, and hence cpi->ref_frame_flags will have the ALTREF
bit clear, as computed by get_ref_frame_flags in encoder.c.
sf->alt_ref_search_fp forces the previous ALTREF frame to
be used as the only possible reference when encoding a new ALTREF
frame, but due to cpi->ref_frame_flags, some buffers will not be
initialized (see rdopt.c:7689 yv12_mb), leading to a segfault.
get_ref_frame_flags in encoder.c has been changed to prefer to keep
the LAST frame, then the ALTREF frame, then any of the LAST{2,3,4}
frames and then the GOLDEN frame in that order of preference in case
any of them are the same. This avoids the segfault and behaves the
same for the baseline.

This was never hooked up for the 32x32_34 case as the neon_asm version
in 3f7c12da, when the intrinsics version was added.

This avoids repeatedly checking the candidate motion vector
precision level at the decoder end. The compression performance
varies at 0.01% level.

* changes:
Branch dct to new implementation for bd12
Change dct32x32's range
Fit dct's stage range into 32-bit when bitdepth is 12
Pass tx_type into get_tx_scale
Skip transform type search in modes with ref_mv_idx > 0. This
brings down the additional encoding time cost due to the DMR system
from 32% to 17%, at minimal coding performance regression.

Fix several use cases where MAX_MV_REF_CANDIDATES is mixed up with
is_compound flag to avoid potential coding interruption.
Change-Id: Ifdee1ef8a81ef6d1c155315c6c6a3074aa7a8b5e
Change recursive weight for average_source_sad and
put some constraint on spacing between detected scene-cuts.
Change only affects 1 pass real-time mode.

Do not consider 4x4 transform when the maximum possible transform
size is 32x32.
Overall encoding speed is increased by more than 10%. Compression
performance is neutral on lowres, midres, and hdres.

The VP8_EFLAG_NO_UPD_LAST and VP8_EFLAG_NO_REF_LAST flags can be
passed to the encoder to signal that it should not update/reference
the LAST ref frame when encoding the current frame. With
--enable-ext-refs turned on, the new LAST2 LAST3 and LAST4 ref frames
could still be used or updated, which causes the
VP10/ErrorResilienceTestLarge.DropFramesWithoutRecovery/{0,1,2}
tests to fail.
With this patch, if --enable-ext-refs is used, then
VP8_EFLAG_NO_UPD_LAST and VP8_EFLAG_NO_REF_LAST also applies to the
new LAST2 LAST3 and LAST4 ref frames, as well as the LAST ref frame.
