2a180c69ea Save a register (or regsize of stackspace for x86-32) for the no-loop 
mbedge loopfilter functions, by re-using space that holds a variable
that we no longer need.

bcd4aa6498 Use nested ifs instead of &&, which appears to not work with %ifidn (i.e. this 
construct was always enabled, even for <ssse3 versions).

2208053bd3 Split pextrw macro-spaghetti into several opt-specific macros, this will make 
future new optimizations (imagine a sse5) much easier. Also fix a bug where
we used the direction (%2) rather than optimization (%1) to enable this, which
means it wasn't ever actually used...

3aace1bcac Rename av_transcode() to transcode(). 
av_ prefix is reserved for libav* libraries functions, it is confusing
to use it for an application function.

e3f7bf774c Fix SPLATB_REG mess. Used to be a if/elseif/elseif/elseif spaghetti, so this 
splits it into small optimization-specific macros which are selected for each
DSP function. The advantage of this approach is that the sse4 functions now
use the ssse3 codepath also without needing an explicit sse4 codepath.

496c645d3b Never shrink the ByteIOContext buffer in ff_rewind_with_probe_data 
If there is little unread data in the ByteIOContext buffer, this may lead
to reducing the size of the ByteIOContext buffer to little more the probe
data size. This can lead to suboptimal aviobuf behaviour, e.g. making some
demuxers fail to do short seeks backwards (if the input isn't seekable).

3611e7a309 Inline asm for VP56 arith coder 
This is a lot more reliable to get cmov rather than trying to trick gcc into
generating it, useful since it's 2% faster overall.

fe1b5d974a Decode DCT tokens by branching to a different code path for each branch 
on the huffman tree, instead of traversing the tree in a while loop.

Based on the similar optimization in libvpx's detokenize.c
