[IL2CPP] Build fails if trying to assign a default value to a function's reference parameter ("in" keyword)

IL2CPP

-

How to reproduce:
1. Open the attached project
2. Build the project with "IL2CPP" Backend

Actual result: The build fails.
Expected result: The build succeeds.

Reproducible with: 2019.3.0a11, 2019.2.1f1, 2019.1.14f1, 2018.4.6f1.

Notes:
- The issue happens when assigning a default value to a reference parameter (C# 7.2 "in" keyword)
- The issue is not reproducible if assigning "null" as default value
- The build succeeds if using "Mono" backend
- The build fails with error:
IL2CPP error for method 'System.Boolean Test::TestFunction(System.Int32&)' in assembly 'C:\Users\[USERNAME]\Desktop\ReproProject\ReproProject\Temp\StagingArea\assets\bin\Data\Managed\Assembly-CSharp.dll'
Additional information: Specified argument was out of the range of valid values.
