offsetting by a variable stride prevents instruction reordering,
resulting in poor assembly.
additionally reroll 16x16/32x32 loops to reduce register spill with this
new format

This patch reduced the BLOCK_8X8's intra_cost_penalty, which
allows 8x8 blocks to conduct intra mode search. Borg test
result(rtc set): 0.077% PSNR gain, 0.228% SSIM gain. No speed
changes.

The rotation computation using 2X of cos(pi/16) has a potential to
overflow 32 bit, this commit disable the function to allow further
investigation and optimization.

Calculated cpi->vbp_threshold_sad from this frame's dequant value.
The encoding quality and speed didn't change much. Borg test
result: PSNR: -0.002%, SSIM: -0.003%.

The version is currently producing different result from c version
for some input. Disable the use of it for now to allow time for
investigation the source of mismatch.

The default golden frame interval was doubled. After encoding a
frame, the background motion was measured. If the motion was high,
the current frame was set as the golden frame. Currently, the
changes were applied only while aq-mode 3 was on.
Borg tests(rtc set) showed a 0.226% PSNR gain and 0.312% SSIM gain.
No speed changes.

structured extended feature flags require eax = 7; avoids incorrectly
detecting avx2 on some older processors that support avx.

For color sampling format other than 420, valid partion size in Y may
not work for UV plane. This commit adds validation of UV partition
size before select the partition choice.
This fixes a crash for real time encoding of 422 input.

For the test clip used, the decoder performance improved by ~2%.
This is also an intermediate step towards adding back the
mode_info streams.
