This commit makes the encoder to use different frame context index
for different frame types. In the baseline setting, it sets the
frame context index of the overlay frame to be different from other
regular inter frames. In the ext-refs setting, it further allows
the backward reference frame to use a different index.
It improves the compression performance for both settings.
Baseline
lowres 0.12%
ext-refs
lowres 0.50%
midres 0.56%

everything outside of third_party should follow 'PointerAlignment:
right' i.e., associate the '*' with the variable

The LLVM trunk has reached 4.0 and now __clang_major__ is not enough
to distinguish between old XCode Clang and the new 'real' Clang.
Using __apple_build_version__ allows to make this distinction.

needed to avoid hard coding targets here.

remove some (but not all yet!) tuple mis-use, and revamp the code a lot.
Factorize some common chores into MainTestClass.

Set adaptive_rd_thresh to 0 at speed 0. This allows a thorough mode
search, and eliminates a blocking artifact seen in an encoder test.
Borg test:
1. lowres
Overall PSNR: -0.135%; SSIM: -0.293%;
2. hdres
Overall PSNR: -0.122%; SSIM: -0.208%;
Encoder speed tests: 2% - 6% slower.

Added a new expt rect-tx to be used in conjunction with ext-tx.
[rect-tx is a temporary config flag and will eventually be
merged into ext-tx once it works correctly with all other
experiments].
Added 4x8 and 8x4 tranforms for use initially with rectangular
sub8x8 y blocks as part of this experiment.
There is about a -0.2% BDRATE improvement on lowres, others pending.
When var-tx is on rectangular transforms are currently not used.
That will be enabled in a subsequent patch.

- HBD encoder speed improvement (SSE4.1):
Enable CONFIG_VP9_HIGHBITDEPTH, on Xeon E5-2680,
50 frames, park_joy_1080p, 12-bit,
Encoding time reduces from 4846481 to 4177471 (ms)
- Add unit test to verify bit-exact and EOB calculation
