The x86 runs short on registers because numerous elements are not static.
In addition, splitting them allows more optimized code, at least for x86.

  dcadsp: add int8x8_fmul_int32 to dsp context

See: 481a46a4Merged-by: NMichael Niedermayer <michaelni@gmx.at>

It is currently declared as a macro who is set to inlinable functions,
among which a Neon and a default C implementations.

Add a DSP parameter to each inline function, unused except by the
default C implementation which calls a function from the DSP context.

On an Arrandale CPU, gain for an inlined SSE2 function vs. a call:
- Win32: 29 to 26 cycles
- Win64: 25 to 23 cycles

This makes the generated assembly more internally consistent,
avoiding declaring two labels for the same function (for cases
where EXTERN_ASM is empty) and not declaring a separate unprefixed
label in other cases.

This also makes sure the .func and .type delcarations have the same
prefix. They have previously not been used on the platforms
that have prefixed symbols on arm (iOS), but gas-preprocessor
has recently started using the .func declarations for adding
.thumb_func declarations for such functions.

remove the test for it explicitly for these architectures.

If a special comment packet shows up in the middle of the stream, we
should extract it out into the vorbis stream metadata dictionary.

Also, if there is metadata in the packet on the way in, it might linger
since we only add data to the dictionary causing stale metadata to be
inserted into the stream. Instead, clear it to remove any doubt about
what is new and old.
