Add inverted lags index to simplify the loop in
`FindBestPitchPeriod48kHz()`. Instead of looping over 294 items,
only loop over the relevant ones (up to 10) by keeping track of
the relevant indexes.
The benchmark has shown a slight improvement (about +6x).
Benchmarked as follows:
```
out/release/modules_unittests \
--gtest_filter=*RnnVadTest.DISABLED_RnnVadPerformance* \
--gtest_also_run_disabled_tests --logs
```
Results:
| baseline | this CL

This CL also moved `PitchPseudoInterpolationInvLagAutoCorr()`
into `FindBestPitchPeriod48kHz()`.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.
Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.
The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.
Development
See here for instructions on how to get started developing with the native code.
