[iOS] Performance regression on iOS introduced in 2017.3.0 alpha
Reproduction Steps:
1. Open User's project
2. Build for iOS (development build)
3. Deploy to an iOS device
4. Attach Unity profiler
5. Notice the difference in CPU usage
Approximate test results:
Unity 2017.1.3f1 - CPU ~2.3 ms
Unity 2017.2.1p4 - CPU ~2.3 ms
Unity 2017.3.0a1 - CPU ~6.8 ms
Unity 2017.3.0a4 - CPU ~6.5 ms
Unity 2017.3.0a5 - CPU ~33.3 ms
Unity 2017.3.0p3 - CPU ~33.3 ms
Unity 2018.1.0b4 - CPU ~33.2 ms
Expected Behaviour: Similar CPU/GPU with different Unity versions.
Good performance: Unity 2017.1.3f1, 2017.2.1p4
Worse performance: Unity 2017.3.0a1, 2017.3.0a4
Current performance: Unity 2017.3.0a5, 2017.3.0p4, 2018.1.0b4
