[Android] Calls from native Android library via registered callbacks are significantly slower when built with IL2CPP
To reproduce:
1. Download and open attached project.
2. Build and run on any android device.
3. Check the logs via ADB logcat.
4. Notice the outputted logs with the TIME label.
Expected result: Time outputted should be less than 1ms.
Actual result: Time outputted varies from 8 ms to 25 ms depending on the device.
Reproduced with: 2018.2.0a1, 2018.1.0b8, 2017.3.1p1, 2017.2.1p4, 2017.1.3p1, 5.6.5p2
Devices under test:
Google Nexus 4*, OS:5.1.1, CPU:armeabi-v7a, GPU:Adreno (TM) 320,
Build:google/occam/mako:5.1.1/LMY48T/2237560:user/release-keys
Google Pixel 2 XL*, OS:8.1.0, CPU:arm64-v8a, GPU:Adreno (TM) 540,
Build:google/taimen/taimen:8.1.0/OPM1.171019.018/4518263:user/release-keys
Samsung SM G930F*, OS:7.0, CPU:arm64-v8a, GPU:Mali-T880,
Build:samsung/heroltexx/herolte:7.0/NRD90M/G930FXXU1DQJ3:user/release-keys
Notes: Issue does not reproduce with Mono scripting backend. With mono, time to finish the call is mostly around 0.00005 which is less than a millisecond.
