Ari Koivula f098e46f4f Add a more realistic speed test for inter sad 
Inter SAD accesses pixels directly from the frame buffers, so give it
a 4k frame to work in for more realistic results. The old test used
intra test data, which consist of tiny buffers.

Ari Koivula ce34b73505 Merge branch 'mvd-fixedpoint' 
Measured a cumulative effect of 1.04x speedup, when inter search is
used a lot. Not a huge difference.

Ari Koivula 9ea7bfd19a Return calls per second from speed tests 
Sometimes the tests overrun their time limit by varying amounts.
Return calls per second based on the amount of time actually spent in
the loop instead of how much time we tried to spend in the loop.

Ari Koivula 07a919cb3e Add speed tests for dual intra SAD functions 
The speed test suite was crashing due to these being missing.

Ari Koivula 345ef833d7 Add more tests for inter SAD 
The existing tests only covered the edge cases of border extension, but
not the SIMD optimized versions of reg_sad. This adds proper tests for
current optimized reg_sad implementations and ones we are likely to
have in the future.

Ari Koivula a4ba794587 Optimize get_ep_ex_golomb_bitcost 
Arrange the decision tree such that there is only 3 branches on the
most common paths and the more likely branch is always fall-through.

A profile guided optimization pass would probably do something similar.

Ari Koivula 82cfab58f8 Improve fast mvd coding cost estimation 
A lot of time is being taken up by this function on ultrafast, and it
doesn't do a very good job. This change aims to both simplify the
logic and make the estimate better.

The logic is simplified by using a look up for the step mvd bit cost
step function instead of mimicking the binarization process. The
estimation is made better by checking fractional cabac bit costs.

The new function returns the same results as
kvz_get_mvd_coding_cost_cabac, but is also faster than the old
function.

Ari Koivula 4ec039004b Add monochrome encoding 
Write bitstream without chroma when encoding with --input-format=P400.
This reduces bitstream size by 0-1 %, compared to coding monochrome in
420 format, and speeds up encoding slightly due to not processing
chroma.
