428984b041 Another micro-optimization for unpack_vlcs(): Eliminate a possible
branch and save around 45k-55k dezicycles per function run.

4c0dda2b3f Check codec_id and codec_type in avcodec_open(), based on 43_codec_type_mismatch.patch from chrome
This is said to be able to lead to a stack based buffer overflow.

138fe83215 Perform the DC prediction reversal immediately after decoding all of
the DC coefficients. This has a greater probability of leveraging the
coefficients while they are still cached.

When testing with the Big Buck Bunny 1080p video, I consistently saw
improvements of 500k-600k dezicycles per run (through
reverse_dc_prediction()) thanks to this move.

40e26453c4 Use a custom radix sort implementation instead of qsort in dnxhd encoder.
This is mainly to avoid test failures due to implementation-defined
behaviour of qsort when elements are equal, giving different results
for each of FreeBSD, Linux/glibc and Solaris.
In addition it is about 35 % faster, effect on overall speed is minimal
though (< 2%).
Regression tests are unchanged (i.e. identical to Linux/glibc).

The DECLARE_ALIGNED_8 macro is defined to align to 16 bytes instead

macro ever need 16-byte alignment, cases which once did having been
changed to always specify 16 bytes explicitly.

2f17f9c10c 1.5x faster ff_vorbis_floor1_render_list, 5% faster vorbis decoding on Core2.
1.3x and 3% on G4.
Though I think only part of this speedup is due to my optimizations per se;
some of it is that I got a better roll on the GCC random code generator.
Trivial reorderings of this function have a disproportionate effect on speed.

21c6a0258c Remove useless alignment from MpegEncContext.intra_scantable
The first member of struct ScanTable is a simple pointer, extra alignment
of which serves no purpose.  The alignment specifier was added along with
some Altivec optimisations also adding a 16-byte-aligned array at the end
of struct ScanTable.  Presumably the redundant, outer alignment was added
by mistake.  The inner one is clearly sufficient.

afe08a728a PPC: remove unnecessary alignment on local variables
Storing a single element from a vector where all elements have the same
value does not require an aligned destination.  Which element is stored
depends on the alignment of the destination address, but since they all
have the same value, the result is the same regardless of the alignment.
