[roll] Roll fuchsia [audio_core] Optimizations to squeeze out a bit more performance Optimizations: 1. Logging is not free: even when the log level is disabled (such as TRACE), the log message is still constructed. Hence, every log statement on the critical path should be wrapped with a constexpr guard. 2. Avoid some duplicate computation in MixStage::ForEachStream. 3. In stream2::ReadableStream::Trim, don't call TrimImpl unless we are trimming something new. This improves output pipeline benchmarks on nelson by about 3% over ToT, but the follow-up CL (fxrev.dev/478521) improves by 25%-30%. After this CL, fxrev.dev/478521 is still slower than ToT, but only by about 10%. I believe the remaining 10% comes from repeated calls to Also, fix a small bug that got accidentally added to the last patchset of fxrev.dev/639969.

This repository contains Fuchsia's Global Integration manifest files.
All changes should be made to the internal version of this repository. Our infrastructure automatically updates this version when the internal one changes.
Currently all changes must be made by a Google employee. Non-Google employees wishing to make a change can ask for assistance via the IRC channel #fuchsia on Freenode.
First install Jiri.
Next run:
$ jiri init $ jiri import minimal https://fuchsia.googlesource.com/integration $ jiri update
Third party projects should have their own subdirectory in ./third_party.
