Update our opus implementation to a prerelease of 1.1. This brings many performance and encoder improvements and we believe it is stable enough to switch. This import does not enable any of the new assembly optimizations. The imported code is https://git.xiph.org/opus.git master commit f2446c25c6519bae190152f7a579310b83dc43fd.
