Reproduction steps:
1. Open "1177601" project
2. "Player Settings" -> "Configuration" -> "Scripting Backend" -> "IL2CPP"
3. "Player Settings" -> "Configuration" -> "Target Architectures" -> "ARMv7"
4. Build & Run for Android
5. Note the "timePerStack" (~0.13ms)
6. "Player Settings" -> "Configuration" -> "Target Architectures" -> "ARM64"
7. Note the "timePerStack" (~3.70ms)

[Android] ARM64 architecture takes longer to execute StackTrace API than ARMv7, especially on low-end devices

Expected Result: ARM64 and ARMv7 architectures perform similarly
Actual Result: ARM64 architecture takes longer to execute StackTrace API than ARMv7

Reproduced with: 2020.1.0a2(~1.3ms), 2019.3.0b1(~1.3ms), 2019.2.3f1, 2019.1.14f1, 2018.4.7f1, 2017.4.32f1

Note:
Newer phones handle this better with less an effect; Issue most prominent in low-end devices
