This reinstates the tests from commit
efda2831 with the appropriate
fixes for 32 bit x86 builds.

- Use int32_t instead of int in vpx_obmc{variance,sad} functions
- Remove weigthed_src and obmc mask strides and assume contiguous
  buffers. These inputs can always be packed as contiguous arrays.

Originally we need to send the refresh flag and the virtual indices
mapping for the reference frame buffer update for show_existing_frame to
have the BWDREF_FRAME replace the LAST_FRAME.

To remove sending this information, we update the the virtual indices
of the reference frame buffer after the last_bipred_frame is encoded,
and therefore the decoder will receive the updated reference mapping
at the next non-show-existing frame.

As a result, we can save 4 bytes per show-existing frame, and get 0.12,
0.2, and 0.07 BDRATE improvement in lowres, derf, and midref test set
respectively.

Reject ext-inter compound modes before doing full rate distortion
evaluation, if the corresponding single reference modes had a lower
modelled RD.

ext-inter speedup up to TBD.

Coding performance: TBD

This offset value related to the bit depth has been taken care of
inside the function vp10_highbd_block_error.

Commit 0d6980d7 removed some use
of the skip_txfm optimization, and the rest are not productive.

The current use of this optimization is only used with --good
and --cpu-used >= 3, however the overhead of this is higher than the
speedup it yields.

Removing this, and subsequently simplifying model_rd_for_sb yields
a net encoder speedup:
--cpu-used=0    ~1.5% faster
--cpu-used=3    ~2.0% faster

The code simplification is also significant.
