Any chance of someone finding the time to have a look at this?

(There is a small issue that is now being treated differently:
The earlier code would record a position in a buffer that
is being written to via put_bits(), then write data,
then overwrite the byte at the position recorded earlier
and only then flush the PutBitContext. In case there was
no writeout
The PutBitContext has already been flushed a few lines above
and nothing has been written to it in the meantime.

ff_square_tab is always used with an offset; if this table
is marked as hidden, the compiler can infer that it and
therefore also ff_square_tab + 256 have a fixed offset
from the code. This allows to avoid performing "+ 256"
at runtime by baking it into the offset from the code to
the table.

This codec uses BswapDSP, BlockDSP and IDCTDSP.
The former never used MMX, the latter does not use it

These matrices are only used for MJPEG, not for LJPEG.
So only check them for the former. This is in preparation
for removing said matrices from LJPEG altogether
(i.e. sending NULL matrices).

We currently mostly do not empty the MMX state in our MMX
DSP functions; instead we only do so before code that might
be using x87 code. This is a violation of the System V i386 ABI
(and maybe of other ABIs, too):
