Anton Mitrofanov e786649568 Fix CAVLC encoding 
This bug mainly occurred when encoding with high bitrate (low QP).
It did not occur when encoding in baseline or main profile.

Janne Grunau 8bd6d28025 aarch64/asm: optimize cabac asm 
0.5% - 2% overall speedup on
`./x264 --threads X --profile high --preset veryfast --crf 15 -o /dev/null park_joy_420_720p50.y4m`
cabac is responsible for roughly 1/6 of the CPU use.
Branch mispredictions are reduced by 15% to 20%.

cortex-s53: 0.5% faster
cortex-a72: 2%  faster
neoverse-n1: 0.9% faster

Janne Grunau 8578bd9f7f aarch64/asm: optimize cabac_encode_terminal with extrinsic knowledge 
Approach taken from x86 asm. Overall speedup meaningless.
cabac_encode_terminal on average twice as fast on cortex-53 while
encoding with following command:
./x264 --threads 1 --profile high --preset veryfast --crf 15 -o /dev/null park_joy_420_720p50.y4m

Less relative speedup on cortex-a72/73.

calls to malloc/free.

This fixes building with MSVC targeting WinRT.
