Andreas Rheinhardt 4367c055b6 avformat/cafenc: Fix segfault upon error, avoid indirection 
caf_write_deinit() would segfault if the CAFStreamContext
couldn't be allocated. Fix this by moving everything from
CAFStreamContext to the ordinary CAFContext; the separation
doesn't make sense for a format with only one stream anyway
and removing it also avoids an indirection.

Martin Storsjö 7ebb6c54eb tools: Lowercase more patterns in aarch64 assembly 
Match more SVE/SME specific details.

Also lowercase all register names. As this matches many cases
of code comments that refer to variables elsewhere, not specific
registers, we only apply this tranformation on the part of lines
before a potential comment.

Martin Storsjö f74c551eaa aarch64: Fix indentation of a few instructions 
This file is excempt from the indent checker script, as there
are a few other bits in it that the script wants to reformat
into slightly worse form, or which might not warrant being
reformatted.

But these instructions should indeed be indented this way.

James Almer 7581abdcb1 avformat/cafenc: support writing Packet Table Chunk Header if there are priming or remainder frames 
If a codec has fixed block_align and frame_size but a given sample has either
priming or remainder frames, a pakt chunk can be written declaring zero packets
and no table, reporting only the samples to be discarded.

Andreas Rheinhardt 2729c52988 avcodec/x86/hevc/deblock: Reduce usage of GPRs 
Don't use two GPRs to store two words from xmm registers;
shuffle these words so that they are fit into one GPR.
This reduces the amount of GPRs used and leads to tiny speedups
here. Also avoid rex prefixes whenever possible (for lines
that needed to be modified anyway).
