HEVC spec has CRA frame which allows random access with open GOP, hence
it can achieve higher compression efficiency.

Although the DSP function only uses single precision from RISC-V F, the
caller may leave double precision values in the spilled registers if the
calling convention supports double precision hardware floats. Then, we
need to save and restore FS registers as double precision.
Conversely, we do not
This also allows the compiler to optimize the implicit
checks performed by the PutBit-API away (Clang does so).

Removed unnecessary comment as requested by Ronald S. Bultje.
some more thoughts about the patch:
This is my deduction from what I could find - There was a hard limit of 16
threads in libvpx as there was no benefit to adding more threads based upon
the parallelism available in the the codec.
This change improves the performance and multicore scalability of the vp9
codec for streaming single-pass encoded videos by taking advantage of up
to 64 cores in the system. The current thread limit for ffmpeg codecs is 16
(MAX_AUTO_THREADS in pthread_internal.h) due to a limitation in H.264 codec

We can't get Shift from bit depth for some formats in the SDK. For
example, bit depth is 10, however Shift is 0 for Y410 (XV30 in FFmpeg).
In order to support these formats in the next commits, this patch
