This avoids reloading them if they haven't been clobbered, if the
first pass also was idct.
This is similar to what was done in the aarch64 version.

Since the same parameter is used for both input and output,
the name inout is more fitting.
This matches the naming used below in the dmbutterfly macro.

The clobbering tests in checkasm are only invoked when testing
correctness, so this bug didn't show up when benchmarking the
dc-only version.

The latter is 1 cycle faster on a cortex-53 and since the operands are
bytewise (or larger) bitmask (impossible to overflow to zero) both are
equivalent.

Since aarch64 has enough free general purpose registers use them to
branch to the appropiate storage code. 1-2 cycles faster for the
functions using loop_filter 8/16, ... on a cortex-a53. Mixed results
(up to 2 cycles faster/slower) on a cortex-a57.

Seemingly ff_clear_block_sse assumed that the block array is aligned,
so make sure it is.

when hlsenc use flag second_level_segment_index,
second_level_segment_size and second_level_segment_duration,
the rename is ok but the output filename always use the old filename
so move the rename operation after the close the ts file and
before open new segment

avfilter_graph_request_oldest() does work that should be done by
either the filter or the application.
The principle of this function, calling ff_request_frame() from
outside the filter was always shaky. This version is less elegant
since it requires making special cases for each filter, but it
is more robust since it no longer calls ff_request_frame()
directly without notifying the filter.
Eventually, avfilter_graph_request_oldest() will be deprecated
for a function to just run the graph.
Unlike av_frame_is_writable(), it uses the link's alloc callback,
making direct rendering possible.
The code comes from ff_filter_frame_framed(), moved with mostly
trivial changes.
