Collect the 16-bit signed range sample clipping routines scattered about, which can be optimized on armv6 and create firmware/export/dsp-util.h (for lack of better place right now).

Get rid of strict aliasing warnings for ARMv6 spc_dsp.c. Just do load in asm block instead.

Centralize the selection of codec compilation flags to codec.make
to avoid having to duplicate the per cpu selection logic and the
build rule in the individual codec lib make files and make tweaking
easier.

The two special cases, libmad and libspeex were left alone.

I plan to introduce a var for arm generation so that appropriate flags
can be selected per generation as benchmarking results have shown that
different arm arches might have different optimal flags.

SPC Codec: Restore correct FIR buffer alignment when an address mask is used. It must be FIR_BUF_ALIGN. Fix Coldfire assembly constraint where an input parameter was also being written.

S5L870x is fast enough to play spc with gaussian interpolation and echo processing.

FS#12113: Optimize IRAM configuration for SPC. Performance increases by 5-6% on PP5022, PP5024 and S5L870x. No change of performance on Coldfire, PP5002 and PP5020.

SPC Codec: AS3525 targets should be fast enough for realtime BRR decode and echo.

SPC Codec: Was broken on ARMv6 since EABI switch and somehow I failed to notice in the first place (and so did eveyone else it seems :). Some early-clobber constraints were needed on inline assemebly operands. In some places, they aren't necessary where they were used, so remove those.
