[opus] 2 patches related to silk_biquad_alt() optimization

[Linfeng Zhang]

Hi Ulrich,

As Jean-mark recommended, we created "--enable-check-asm" config option to
active OPUS_CHECK_ASM macros in the optimization, where the C function is
called inside and the results of C and optimization functions are compared
when encoding/decoding the real audio files.

Thanks,
Linfeng
