opus: Add Special Hybrid Folding (per RFC8251)

This decoder-side change, introduced in RFC 8251 (section 9), slightly
improves the decoded quality of 16kbps speech in Hybrid Mode.

Differences can be seen/heard in testvector05.bit, testvector06.bit,
and testvector12.bit in the RFC 6716/8251 testvectors found here:
