How to reproduce:
1. Open the "mono_profiler_coverage_crash.zip" project
2. Enable Code Coverage (Preferences > General > Enable Code Coverage)
3. Restart Unity
4. Open Test Runner (Window > Test Runner)
5. Run the "EditorTests > Tests > GetCoverageStats_ForMethod_DoesNotCrash_FAILS" test

Actual Result: Unity crashes.

Reproducible in: 2020.1.0a4, 2019.3.0b3, 2019.3.0a12.
Regression introduced in: 2019.3.0a12.
Not reproducible in: 2019.3.0a11, 2019.2.6f1.

Notes:
- 'mono_profiler_get_coverage_data' fails on certain methods with 'Method has zero rva assembly:UnityEditor type:<unknown type> member:(null) signature:<none>'.
- It might be connected with the [RequiredSignature] attribute. See the attached test case for a list of all methods that fail.
- Coverage doesn't exist in Unity 2019.1 and lower.

Fixed in 2020.1.0a8, 2019.3.0b9.
