audiorsample: Fix build on 32-bit x86
...
Turns out _mm_cvtsi128_si64() isn't available on 32-bit, so only build
SSE 4.1 optimisations on x86-64 for now.

audioresample: Separate out CFLAGS used for SSE* code
...
This makes sure that we only build files that need explicit SIMD support
with the relevant CFLAGS. This allows the rest of the code to be built
without, and specific SSE* code is only called after runtime checks for
CPU features.

...
The latter is only available on x86-64 for some reason.

audio-resampler: avoid some format conversion
...
Store the filter in the desired sample format so that we can simply do a
linear or cubic interpolation to get the new filter instead of having to
go through gdouble and then convert.
