9021d09f9a Remove some dead code in CLPF. 
av1_clpf_frame() was always called with the same src and dst,
so we only need one argument and the code supporting different
src and dst was removed.

e8224c7ad5 Reduce memory footprint for CLPF decoding. 
Instead of having CLPF write to an entire new frame and
copy the result back into the original frame, make the
filter able to work in-place by keeping a buffer of size
frame_width*filter_block_size and delay the write-back
by one filter_block_size row.

This reduces the cycles spent in the filter to ~75%.

9ed9cedae1 Remove -fno-strict-aliasing flag 
The referenced bug was fixed by saving neon registers. That this had any
effect was coincidental.

Both chromium and Android build with clang and neither uses this flag.

8205b78552 Make ref_mv_idx syntax context dependent on block distance only 
This allows the hardware decoder to start decoding ref_mv_idx
syntax prior to the sorting stage and hide the latency of entropy
decoding. The compression performance change is about 0.01% level.
