The floating-point optimizations are not bit exact with C functions,
because of the different orders of floating-point operations.
But they are bit exact with the simulation C functions which simulate
the floating operations in the optimizations.

Should call celt_inner_prod().
This requires the API change of celt_pitch_xcorr() by passing in
"arch".

We tested on x86 and arm, and got bit exact results as original.

Should call celt_inner_prod().

This change is bit exact as original, except for x86 floating-point.
In x86 floating-point, it calls celt_inner_prod_sse() which may have
different output with the change of floating-point operations' orders.

It's unnecessary, and isn't defined correctly on floating-point.

This makes us correctly use Neon functions (in floating-point mode) on
platforms where Neon is detected by RTCD.

We boost bands that either cause leakage or are filled with leakage

Now scaling the energy to the same value is would be in floating-point

It seems like letting CBR use up to 2/3 of the bit is still a win

Thanks to petrufm for pointing that out:

This makes it possible to run the testvectors with asan enabled.

We now include the object files for those rather than attempt to

And run the build request only at the last configuration.
Also add a check if api_key is unset to not try to request a new build.

The appveyor script needs an encrypted api key to trigger
downstream builds, and there doesn't seem to be an easy
way to make the builds we run for the main repo something
other contributors can control.

Less clutter on systems that hide dotfiles.

Signed-off-by: Ralph Giles <giles@thaumas.net>

The code would have run fine on 32-bit archs, but would have overflowed
on a 16-bit arch

Some informal tests seem to confirm that reducing the trim at 32-64 kbps
improves quality (better HF). It's not clear whether it's also the case
at 96 kb/s and above, so we're leaving it as is for those rates.
