SILK was being allocated too few bits for stereo hybrid, often resulting
in forced narrowing of the width. We now allocate more bits to SILK
and reduce the threshold for narrowing. This improves quality enough that
the bitrate threshold for switching to SILK can be increased to 44 kb/s.

Distinguish source files for the SSE 4.1 instruction
set extension consistently by their filename. This makes
it easier to check the correct flags are being set at

some SSE optimizations were using an instruction sequence that required
128-bit alignment, even though this is not always guaranteed. The error
was in handling a 64-bit entity; made the same macro changes that had
been done previously for 32-bit entities.

|frame_size_enum| in tests/test_opus_encode.cl:117 is flagged as potentially
uninitialized but get_frame_size_enum() will fail anyway if a valid value is
not found.

Migrating opus-codec.org to a static site generator inserted
a redirect into the download path, which the actual testvectors
at https://opus-codec.org/static/testvectors/opus_testvectors.tar.gz.

Add the -L option to the suggested curl invocation so the redirect
is followed to download the actual resource. Without this one
gets the html redirection fallback page.

The new detector for SWB vs FB is unreliable due to the hack
that was required to get 24 kHz analysis working. We're now err
on the side of FB just to make sure.

Uniform layout is easier for external tools to parse,
especially maintaining one source file per line.

Both versions of silk/tables_NLSF_CB had symbols
named silk_NLSF_CB1_Wght_Q9 which causes problems
if both files are build as part of the same
compilation unit. Rename the wideband version
to include a 'WB' string to avoid the conflict.

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.
