[IL2CPP] Calling .GetHashCode on instances of empty structs does not return the same value in IL2CPP builds
Reproduction steps:
1. Open the attached project "My project.zip"
2. Make sure the Scripting Backend is set to IL2CPP
3. Build and run on an Android device
4. Observe the AndroidLogcat logs
Expected result: Empty Struct GetHashCode returns True
Actual result: Empty Struct GetHashCode returns False
Reproducible with: 2019.4.37f1, 2020.3.31f1, 2021.2.16f1, 2022.1.0b12, 2022.2.0a8
Reproducible with these devices:
VLNQA00176, Xiaomi Redmi 4 (Redmi 4), Android 6.0.1, CPU: Snapdragon 430 MSM8937, GPU: Adreno (TM) 505
----------, Huawei - (ELS-NX9), Android 10, CPU: NOT FOUND, GPU: Mali-G76
VLNQA00264, Samsung Galaxy S10+ (SM-G975F), Android 10, CPU: NOT FOUND, GPU: Mali-G76
Notes:
-Following the same steps with Mono results in the Empty Struct GetHashCode to return True which is the expected result
-Everything seems to be fine for structs with fields
