Also moves the VSHR32() condition outside the loop just in case some compilers
don't optimize that properly.

This reduces the peak decoding error by removing small (inaudible) spikes in
the error at the frame boundaries. These were due to the frequency-domain bias
ending up as a small pulse in the middle of the IMDCT overlap. None of this
was ever audible, but fixing it is still cleaner.

Thanks to Kevin O'Connor for reporting this.

We released 1.1 with 1.1-beta as the hard-coded version.
Hopefully this only affects people doing their own windows builds
 without the git tools available.
Thanks to Ron Lee for the report.

Should make it easier when writing assembly.

Also adds an SSE-optimized celt_inner_prod().

This is a bit faster at -O2 because memcpy()/memmove()/memset() are
vectorized. The code is also cleaner.

gcc is better at optimizing it than the ?: version

NaN detection should now be able to catch values that would create NaNs
further down.

This reverts commit 2446445b.

Also adds denorm avoidance for non-48 kHz rates

This moves some stuff out of the main loop for the unaligned case.

This is a partial revert of c435f06b,
since it didn't actually fix the original problem with shallow clones.
It returns just a hash, not something we (currently) can extract as a
version string in the form things are expecting.

Revision control will remember it for us forever.

I'd commented out mine and stuck azanelli's code in for testing,
 and then accidentally committed it like that.

We were assuming that LDR, LDRD, and STRD could be used on
 unaligned addresses, but this turns out not to be true on really
 old hardware.

This will be removed shortly, but at least it should be correct
 before it goes.
Makes the code get used unconditionally (when uncommented), and
 actually frees the buffer it allocates (now using the libopus
 allocation functions).

The different results for surround were mostly due to a bug in squishyball.

This also splits the rate adjustment between SILK and CELT (previous
code only changed SILK)

Intensity stereo is now based on equiv_rate and should no longer oscillate
in hybrid mode. Also, there is now a separate set of thresholds for
surround tuned by Monty. The non-surround thresholds were also updated at
low bitrate to be closer to what Monty found for surround.

This removes an unused definition warning when compiling without
 custom modes.
